Konstantin the Dayborn — guide

In short

Konstantin the Dayborn is a Legendary Attack champion of the Sacred Order (Dark affinity) built for the Arena: he strips every buff off a target, dumps his own debuffs onto it and hits all enemies twice with partial defence ignore. Build him as a pure nuker — ATK, crit, speed. Outside the Arena he is a very average legendary.

Strengths

• Oath of Silence steals all of the target's buffs before the hit and moves all of his own debuffs onto it — one click removes shields and defensive buffs and hands the enemy your debuff stack.
• Rune Crusher strikes all enemies twice and each hit ignores 10% DEF for every debuff on the target (Parasite, Decrease DEF, Block Active Skills), so a debuff-heavy team greatly boosts his damage.
• Blade of the Sun adds an extra hit on any target that already carries a debuff.
• Arena aura: +30% Ally ATK, which benefits the whole attack team.
• Passive blocks revives of Demonspawn, Undead Hordes and Knights Revenant enemies he kills — as long as Vlad the Dark Warrior is in the team.

Weaknesses

• Nothing for boss fights: no Poison, no HP Burn, no Decrease DEF — hence 2.0 in Clan Boss and Doom Tower.
• All damage is ATK-scaled and depends on the team landing debuffs before his turn.
• The passive is dead weight without Vlad the Dark Warrior in the lineup.
• 105 base SPD with modest DEF and HP — he needs speed tuning and protection from control.

Where to use

Arena first (5.0): an attack nuker who strips buffs and finishes targets. Then Faction Wars (4.5) and Chimera (4.0). In Hydra, dungeons and Hard mode he is mid-tier (3.0), and Clan Boss or Doom Tower (2.0) are simply not his content.

Stats and gear

• Priority: ATK% → C.RATE to 100% → C.DMG 200%+ → SPD.
• Arena targets: roughly 4–5k ATK, 170–200+ SPD; ACC is not a priority (100–150 only if you want the debuff transfer to land reliably).
• Sets: Savage or Lethal together with Crit Damage, plus Speed, Cruel and Perception for accuracy.

Masteries and blessings

• PVE Nuker: Pierce Defenses, Invigorated, Gathering Momentum, Constant Onslaught, Bloodthirsty Prowess.
• For Arena use the PVP Nuker version of the same damage masteries — damage over survivability.
• Relics from the build: Malefic Talon, The Cat's Gaze, Wand of Submission.

Tombs

Book Oath of Silence first (level 5 gives −1 cooldown plus damage), then Rune Crusher, which also gets −1 cooldown at max level. Blade of the Sun only gains damage, so books go there last.

Verdict

A solid Arena nuker for a debuff team, but a very average legendary overall — the site author files him under vault and fusion material unless your Arena is still open.
