Ultimate
Grima Collision
Ultimate Transformation
A transformation technique that turns Eustacia into Eustacia Grima. The 3x3 space centered on Eustacia must be empty to use this skill. On use, Eustacia is replaced by Eustacia Grima; buffs/debuffs from before the transformation are not removed but do not apply — they are maintained with no change to duration, and are hidden. If Eustacia had the Grima of Ruin effect, generate a Grima Barrier - Ruin field over a 9x9 area centered on Eustacia for 4 turns. Eustacia Grima's base stats become 130%~160% of Eustacia's stats at the time of use, rising up to 220% with full Manifestation (Ultimate Enhancement 3); Critical Rate/Damage and Physical Penetration are calculated separately and rise by 50%~80%. Because Eustacia Grima is Eustacia himself, if he dies in this form he does not revive and is treated as dead.
- Grima Barrier - Ruin (4 turns): Enemies inside the area: Max HP -20%, healing effects received and shield effects -50%. Allies inside the area: lifesteal +10%, damage dealt +20%.
- CostTP -RangeSelfAreaSelfCooldown-

Guide
Note: the following is NamuWiki community assessment (KR server), subjective community opinion. No S/A/B tier rating is stated in this article.
- Overview: A crit-focused DPS that is a "glass cannon" but endures via high HP, lifesteal, and revive, and can transform into a monster (Grima). In PVE, especially raids, just equipping Call of Ruin and War God's Thunder-Destroying Prison lets you watch a DPS show every cooldown: HP drops to 1%, then a 100% crit lands defense-ignoring 180% damage, HP returns to 100%, then extra actions (from passive and the exclusive weapon) deal further burst.
- Weakness: still a glass cannon. Damage-reduction lines (defense, damage reduction) are absent at low awakening and only decorative at high awakening, so treat it as effectively none. The design intends him to get hit hard and recover via lifesteal; if you want survivability, invest in HP increase. HP scaling is efficient because passives carry big HP and strong lifesteal but almost no def/res/damage-reduction.
- PVP: Call of Ruin is hard to pick because it hands control to AI, but not using it leaves him short on firepower and TP, which is a downside. With 2-awakening passive strengthening, a viable play is to rush in turn 1, land one War God's Thunder-Destroying Prison, die, gain Collision, then with TP 1 do Grima Collision -> Crushing Blow and die again.
- Class recommendation: Revenant is recommended as the endgame class (grants HP/lifesteal, up to +70% crit rate via lost-HP condition, plus preemptive attack; best synergy with his passive and best survivability among his classes). Striker is passable but rarely adopted (exclusive skills mismatch his kit). Abaddon is a support-type class (buff strip, def/res-down debuff, debuff duration +1) worth using in special situations; it teaches his signature War God's Thunder-Destroying Prison so its raising priority is #1.
- Equipment (community): Armor - since Revenant needs only 30% crit rate, the Crow set plus stacking crit damage is cost-effective; watch not to overshoot 100% crit rate. Alternatively the Assassin set to secure ATK + crit dmg while getting crit rate elsewhere. Accessory - as Revenant, crit rate is very high so the Sawtooth Arrowhead is most suitable; the usual Ancient Shadow Plate is also a good choice.
- Awakening scaling: at 5-awakening and above, the Unique Passive gains the Power of Ruin effect, and the exclusive weapon's Thirst of Ruin gains the Thirst's Reserve shield at turn start when at max stacks. At full Awakening with Ultimate Enhancement 3, Eustacia Grima's base stats rise to 220% (from a base of 130%~160%).

Character review of Eustacia of Ruin by 하막군의게임튜브 · 2026-08-04
The portrait drew complaints for being ugly; the reviewer's position is that it's a dark god and the concept was the point. He didn't pull, so his copy is 3★ and he reads the higher tiers off the manifestation screen. His first real observation is a relief: after a run of characters whose passives read like academic papers, this one is short. (0:00, 0:31, 1:02)
Dark Blood of Ruin: the plan is to die
Attack and Max HP up, a combat attack grants a Collision stack, and dealing lethal damage grants an extra action — and because the wording is lethal damage, it still fires when the target is revived afterwards.
The two held effects are the character:
- Dark Blood of Ruin — one revive per match, at 40% HP rising to 90%. From the first manifestation stage, dying also Fears everything within 2 tiles; Fear scatters a unit and then locks it out of acting.
- Power of Ruin — physical lifesteal, and critical damage scaling with the ratio of health he has lost, up to 50% of it at full manifestation. It's removed by Healing Reversal.
Collision reduces Grima Collision's TP cost by 1 per stack and cuts damage taken by 4% per stack, five stacks maximum — so at five stacks the ultimate is free. And reviving grants Collision at maximum stacks immediately.
Put together, the reviewer's summary is that walking into the enemy line and getting killed on purpose is a legitimate opening: you come back at high health, you Fear everything nearby, and you can transform for nothing. (1:32, 2:02, 2:33, 3:05, 4:38, 5:09)
At the fourth stage he flags one more line worth having: below 20% HP he takes no fixed damage at all. (3:36)
Class: Revenant to hold ground, Abaddon to kill
Revenant is Max HP and physical lifesteal +30%, Crit Rate +30%, and critical damage scaling with lost health for up to another 60% — plus Preemptive Strike whenever he isn't at full health, which he essentially always is. Stacked with the passive that's around +70% critical damage from class alone. He expects most players to run this on a defence deck.
Abaddon is +25% attack and physical penetration, strips two buffs before combat (applying Armour Crack if there are none), +20% damage dealt against a debuffed enemy — he stresses that damage-dealt is a much bigger multiplier than attack — and after attacking, extends every debuff on the target by a turn except action- and skill-control ones.
That last clause makes him a genuine raid pick: the fire attribute had nobody who could stretch debuff durations. Abaddon is fragile enough that he doesn't recommend it on defence, though he allows that people may simply refuse to attack into it. (5:09, 5:40, 6:10, 6:42, 7:14)
The +25% penetration matters more than it looks, because the ultimate carries Crit Rate, critical damage and physical penetration across into the transformed form. He has 55% on gear and says 100% is reachable with the artifact. (7:45)

| Call of Ruin | learned from Revenant | 2 | Self | 3 turns | On use, lose HP equal to 40% of maximum HP (this effect cannot cause death).

While holding this effect, direct control is impossible and the AI takes control. When using an active skill other than the Ultimate, instead of TP, consume HP equal to (TP consumption) x 10% based on the skill's base TP consumption value. Does not die from this effect. • Craving of Ruin Cannot be removed (stack 3, 1 turn): Damage dealt increases by 20%. Maximum HP and physical lifesteal increase by 15% (does not increase with stacking). When an enemy ends its action within 1 ring around, deal 100% of attack power as damage and reduce a stack. |
| Musin Myeolloe-ok | - | - | - | - | itself is 180% ignoring defence, counterattackable but not guardable. He calls it simply a very strong hit and moves on. (11:51, 12:21) |
Grima Collision is a field, not a robot
The transformation works like Lacid Pandragon summoning Arondight, with differences that change how you use it:
- Buffs and debuffs carry over hidden and inactive, but their durations keep ticking, so they can expire while transformed.
- If he holds Grima of Ruin going in, it lays a Grima Barrier - Ruin over a 9×9 for four turns: enemies inside lose 20% Max HP and take halved healing and shields, allies inside gain lifesteal and +20% damage dealt. He rates the field very highly.
- Grima's stats are 130–160% of his own, up to 220% at full manifestation, with Crit Rate, critical damage and penetration carried across at 50%, up to 100%.
- Unlike Arondight, which drops itself after two turns, Grima stays until you cancel it.
- Grima counts as both a player and a Large Monster, and dying as Grima counts as Eustacia dying — the revive does not fire. He notes this makes him very weak to Cyrano Bernstein, on top of the attribute matchup.
- Each turn as Grima adds a stack of Grima Aftereffect: -10% Max HP per stack, permanent, five stacks.
So his recommended line is not to fight as Grima at all. Transform as early as possible, lay the field, attack once, then cancel next turn — cancelling returns his health ratio, keeps the revive intact, and grants an extra turn if the transformation wasn't this turn. The ultimate's cooldown goes up by 3 on cancel, which he accepts: the field is already down and the rest of the team fights on it. (12:51, 13:21, 13:53, 14:23, 14:54, 15:26, 19:04, 19:34, 20:04)
Of the Grima skills, Crushing Blow is 130% in a fan with Neutralize and Armour Crack — modest on paper but respectable once the stat multiplier is applied, and unlike Arondight it inherits crit, so it can spike. Spell of Ruin applies Ruin, which he describes as behaving like Heidelun's Collapse: hit it and it detonates.
Geuk Musin Myeolloe-ok costs 50% of Max HP for +30% penetration and 150% across a 7×7 — and he's blunt that it's a finisher you don't come back from. Grima carries none of his passive, class, gear, artifact or rune effects, so there's no lifesteal to refill him and no revive if he dies. The one way to get lifesteal is to be standing in his own field, which gives 10%. He also checked whether the 50% is taken from the original Max HP or the Aftereffect-reduced one: it's the reduced one. (15:26, 15:58, 16:29, 17:01, 17:31, 18:02, 18:33)
Gear
He runs One Against a Thousand with Envoy of the Storm and calls it taste — full One Against a Thousand is fine too. The alternative is Noble Sword Emperor, taken defensively: fire is a bad attribute right now, with Cyrano Bernstein, Commander Siren Woodville and a freshly updated Roberto de Medici all pointed at it.
Accessory: Black Banner, essentially for the physical penetration. (20:34, 21:04, 26:12, 26:43)
The weapon wants ★5
Fang of Ruin stacks Thirst of Ruin when he takes damage or when an enemy ends its action within 2 tiles: attack and Crit Rate per stack, and at maximum stacks at the start of the turn, a re-action.
The awkward part he demonstrates: a combat attack clears the stacks. You can't realistically avoid attacking, so you need all four stacks in one go — which means being approached and hit, since an enemy that steps adjacent and attacks gives two at once. Two attackers is enough. Anything hitting him from three tiles away gives nothing.
★3 drops the re-action cooldown to 1 and ★5 adds a shield with damage reduction attached, which is where he says it becomes properly worth using. He also points out that the suicide opening feeds it: die in the enemy line, Fear everything, and as the Feared units end their actions within 2 tiles the stacks build for free. (21:04, 21:34, 22:05, 22:36, 23:08)
Runes
All Chaos. He specifically advises against Wind for penetration — take it from the weapon's specialisation instead. (23:08, 23:38)
Artifacts
Warrior's Essence+11 more → carries physical penetration and is a perfectly fine default. Fragment of Ruin is the attacking pick: up to 30% penetration, and an unremovable effect that scales attack as his health drops — which is exactly what the rest of the kit is doing to him anyway. Predator's Chalice is the defensive one: Max HP, physical lifesteal, a heal on kill, and it strips healing blocks outright, since nothing in the game applies one lasting more than three turns.
Attack build takes the Fragment, defence build takes the Chalice. (23:38, 24:08, 24:39, 25:10)
Verdict
At low star levels, lay the field and die — that's the whole plan, and it works. At high star levels players run him differently: charge in, guarantee a kill, die on the spot, and revive with a Fear that locks the area down. Call of Ruin giving up manual control matters less on an attack deck, because the AI will reliably kill something.
Not a must-pull. Worth it if you're short of attackers; skippable if you're saving for the next collaboration, and he notes fire is a poor attribute to be buying into right now. (25:41, 26:12, 26:43)
