Guide: Keberon the Underflame

In short

Keberon the Underflame is a Legendary Attack champion from the Argonites with Force affinity. His main lane is area HP Burn plus single-target finishing: A3 applies HP Burn to all enemies and gives the team +50% ACC, while A2 ignores Unkillable, Shield and 25% of DEF. Build him for damage with enough ACC, and book A3 first.

Strengths

  • A3 is area HP Burn with up to a 100% chance after books, plus a team Increase ACC 50% for 2 turns. Great for Spider, Hydra and Chimera.
  • A2 hits twice, ignores Unkillable, Shield and 25% of DEF, and places Death Seal. If the target dies, it activates A3; if not, he fills his own Turn Meter by 50%.
  • A1 hits twice with a 75% chance to place Decrease DEF 60% for 2 turns; it can also trigger when HP Burn activates on an enemy, once per turn.
  • Passive heals him for 20% of MAX HP when HP Burn activates on an enemy; when HP Burn is removed or expires, it places True Fear for 1 turn. He also brings a 28% Ally ATK aura in all battles.

Weaknesses

  • Fragile base: 15,030 HP, 1,123 DEF and 99 SPD mean he needs team protection and speed.
  • He wants ACC for debuffs and crit damage for damage, so the build is stretched between ACC and nuking stats.
  • Clan Boss and Doom Tower are not his best spots (3.5/5); his area Burn and Death Seal matter less there.
  • A2 and A3 have 4-turn cooldowns; without books and Turn Meter support he can sit idle.

Where to use

Best area is Faction Wars (4.5/5) as a strong Argonite attacker with an ATK aura. Then Hydra, Chimera, Arena, Dungeons and Hard content (4.0/5): in Spider's Den and Sorath he spreads HP Burn and finishes targets. Clan Boss and Doom Tower are average (3.5/5); he is not a priority there.

Stats and gear

Priority: ATK% → C.RATE to 100% → C.DMG → SPD → ACC. Rough targets: 180–220+ SPD, 250–350 ACC for high-end content (lower if your team brings ACC buffs), 100% C.RATE and 200%+ C.DMG, then stack ATK. Sets: Savage, Cruel, Lethal for damage; Perception for SPD and ACC; Stoneskin for Arena; Merciless and Mercurial as strong alternatives.

Masteries and blessings

Main tree is Offense: Pierce Defenses, Foekiller, Piercing Strike, Bloodthirsty Prowess, Boss Slayer. Second tree depends on content: Support for ACC/SPD or Defense for survival. Blessings: Crushing Rend for damage, Temporal Chains or Lightning Cage for control and Arena, Nature Wrath as an alternative. Relics: Malefic Talon, Irethi Coronet, Gorecrescent.

Tombs

Book A3 first: it pushes HP Burn to 100% and lowers the cooldown, and it is his main skill. Then A2 for cooldown and damage so he cycles the finisher and A3 trigger more often. A1 and A4 have no listed book upgrades, so skip them.

Verdict

Keberon is a solid area HP Burn attacker with ACC support and a strong ignore-defense finisher. He shines most in Faction Wars, Spider, Hydra and Chimera; Clan Boss and Doom Tower are not his priority. Build damage plus ACC and book A3 first.
