Guide🔗

Class

• Emperor: recommended to raise first, as it learns the main single-target damage skill Dark Light Kill Slash. Strongest at single-target damage, recommended for hard raids etc.
• Dark Knight: a shared class learning Dark Embrace. Its class passive gives 50% chance to AoE-hit enemies (and guaranteed to adjacent enemies at turn end) a 2-turn -25% Attack/Magic debuff, plus +40% AoE-skill damage. Not bad for Black Prince who dives into enemy lines, but Death Lord is so strong here that this is lowest priority.
• Death Lord: learns Atomic Blast; passive is plastered with balance-breaking effects covering offense, defense, mobility, and debuff, truly a class fit for the strongest in the setting. With Ultimate Grima learned, conditionally he can use teleport twice in a row, making mobility even more absurd. Only downside: if you rush the Death Lord tree, single-target damage is only Chain Flash and Peerless Cleave, so single-target combat is a bit lacking.

Skills

• Dark Light Kill Slash: implements Black Prince's space-cleaving cut; nullifies all defenses (affinity, damage reduction) and ignores revive, dealing 120% Attack absolute damage. If it can't kill, it forcibly banishes, and costs only 2 TP. But because it's absolute damage based on Attack, damage-boosting runes don't apply. After Altair and Zad, it regained fame as the strongest single-target skill (~30k-40k damage ignoring defense, blocking revive). But Iron Mask's release brought an unkillable revive skill that dimmed its glory.
• Atomic Blast: a super AoE that deletes dispellable buffs on targets and nearby, dealing Attack-based damage proportional to buffs deleted; since it deletes everything except undispellable buffs, even artifact effects don't trigger and survivors can't gain buffs. Enemies often get wiped or their combos ruined when Black Prince pops out mid-buff-stacking. With Iron Mask's release, its performance changed to base 50 + 15% physical fixed damage per enemy buff, giving damage exceeding its former peak.
• Asura Skybreaker: simply an Ultimate dealing 175%-200% Attack to enemies within 3 rings around Black Prince (Sharn's was 140%). Multiplier +5% per Awakening level, +10% more via Awakening skill, final 200%; can also add lost-HP-ratio scaling. Enables comebacks in PvE and PvP, benefits from physical penetration; with 100% pen and proper buffs, can one-shot even a max-Awakening tank. Can be enhanced by the unique passive, reviving the old-series feel of mowing down mobs. Genesis 2's screen-splitting animation was also recreated.
• Ultimate Grima: Awakening skill. Teleport to a spot, deal Attack-based fixed damage to a 3x3 area, and gain TP per enemy hit. Considered strong enough to change Black Prince's playstyle: it's a teleport (huge mobility), ignores silence, removes all his debuffs (great escape), and even +20% HP so it doubles as healing. Above all, being a no-cost TP-gain skill it fills TP 5 on turn 1; being AoE, hitting 2 enemies enables Death Lord's re-move. With Vigor buff for re-action, you can secure TP 5, move, and fire Asura Skybreaker on turn 1. Esmeralda's Second Wind can also be used. Being fixed damage, rune skill/AoE damage don't apply. In the Iron Mask season it lost cooldown-reduction eligibility, greatly reducing its rotation and TP supply; its 60% coefficient makes it indirectly nerfed.

Equipment

• Weapon: brought the series-iconic Demon Sword Asura as dedicated weapon; +10% Attack, +10% crit rate at 1-star. True to lore it eats HP at turn start but heals on kill and grants AoE to basic attacks per crit; range is 2 rings (5x5 around target), essentially map-weapon level. The on-kill heal is Black Prince-exclusive; others can use Asura but the -15% turn-start HP is a big burden. For Black Prince the start-HP loss isn't a big penalty since he heals on kill and via passive - true to the original. Weapon awakening only raises skill values, so high awakening is less needed. Alternatives: Durendal, +AoE damage or Moonlight Sword, +0.1% Attack per 1% crit, high ceiling, dispels one debuff per hit so anti-debuff - Moonlight Sword is even said to be better than Asura. Asura's in-game performance is oddly not that great relative to its name-value, which is faithful to the original: its Black Flame AoE is an homage to Genesis 2's Fire Storm on crit while equipping Asura, and this Outer One Black Prince/Asura recreates the Grates-Battle-to-sword-summoning-era Black Prince, who had not yet obtained Ultimate Grima, so Asura was not especially special beyond being a Grima sword. Asura becomes the transcendent "soul sword"/deus ex machina only after Black Prince's death when Ultimate Grima and his power infuse it. With Heidelun's release its performance was buffed, though Black Flame still caps at 3 stacks and depletes fast; still much more usable than before.
• Armor: his own Emperor set exists but is paid-only (a burden). 2-set: +HP and -crit-rate-received; 4-set: +20% crit rate vs enemies with 80%+ HP and ignore affinity in combat. Affinity ignore is good but no Attack/crit-damage/damage options, and affinity ignore doesn't apply to AoE, so it's lacking for peak damage. For AoE damage ceiling, the Crow-costume-motif Crow set (crit rate + crit damage) is recommended ("killed Crow and stole it, true to lore"). The memory-lost costume-motif Poongun set (Attack + survival) is also usable. Attack% not applying to AoE is a downside. The paid Heidelun set (released with Heidelun) gives +30% Attack in combat, which Ultimate Grima, Dark Light Kill Slash, Atomic Blast, and Asura Skybreaker all benefit from; also grants a shield of 50% HP on kill, attractive for Black Prince (largest HP pool among Fighters).
• Accessories: the always-safe Ancient Hero's Ring is recommended; a Stopwatch for cooldown reduction is sometimes used. At Hero grade, Wolf Fang (Attack + penetration) fits. The Black Flag released with Heidelun matches his image but has physical penetration rather than crit, seen as awkward since only Asura Skybreaker among his skills benefits from pen; its special effect also only works when allies fewer than enemies, so poor value, and Ancient Hero's Ring is far better for survivability.

Overall Assessment

• The strongest in the setting; lives up to the title and majesty with formidable power. Previously criticized as excessively pay-to-win, but post-launch there is clearly matching merit ("seems forgiven because he's Black Prince").
• Unlike typical SRPG style, the old Genesis-series charm of mowing down mobs with the Ultimate returned. Opening Ultimate Grima and getting a re-action skill to fire a turn-1 Asura Skybreaker bulldozes even gimmick-heavy fights. He dominates PvP, one-shotting characters who stacked buffs and revives. There were even calls for an Outer One-restricted PvP or limiting Outer Ones to one pick in PvP; the reworked/Inner-Break Iolyn became noted as his PvP counter-pick.
• Only weakness: action-disabling CC like stun. Ultimate Grima ignores silence and clears all debuffs, but a stun landed before that he can't handle alone. Some bring Mind Control as a sniper pick, but landing hard CC is difficult and healers won't sit idle, so it's theoretical. If Moonlight Sword is used instead of Asura, even this can be self-cleared, so he essentially has no weakness.
• Jan 13, 2026 (with new Outer One Sirano's release): slightly buffed. Double Defense and Death Lord defense improved, Ultimate Grima's HP-boost made permanent (a bit more survivability), Dragon Fang slightly buffed. Asura Skybreaker can finally hit enemies beyond dimensions, usable as a main skill again. Ultimate artifact adds +25% AoE skill damage, raising utility (though Ultimate Grima, being fixed damage, sadly can't apply it).
• However Dark Light Kill Slash and Ultimate Grima coefficient issues remain unresolved, so Attack shortage is still hard to fix. For Asura Skybreaker as main, Sirano's dedicated Old Excalibur is much better; for Dark Light Kill Slash as main you must use Emperor + Warrior's Essence. Dragon Fang is essential for survivability, but then you may feel Attack shortage at the crucial moment, so sometimes deploying alongside Deimos is needed.
• Summary (as of January 2026): sturdy but limited without Dragon Fang; with Dragon Fang, whether Emperor or Death Lord, Attack shortage is common, and Ultimate Grima should be used mainly for TP supply + debuff removal, so his majesty is much lower than his prime. Still, Dark Light Kill Slash can reliably delete one target (Emperor standard), Atomic Blast or Black Flame can devastate the enemy line if they land, and the clutch Asura Skybreaker can deal a game-turning finishing blow. Stability dropped a lot but the "pppong" satisfaction remains.
• Aside from performance: post-sword-summoning story centers on Black Prince, so his Deeds section had 24 entries as of Aug 2025. Clearing the story stages in Deeds gives 50 Bits each, so ~1200 Bits payback as of Aug 2025 - unique to Black Prince, and payback will grow as more late Genesis 2 story is added; even a single copy is always worth it ("no way you'd pull and not use him").
