756765576 — guide

In short

Filth is an Uncommon Spirit support from the Demons faction. All he brings is a single-target heal for 10% of the ally's MAX HP (Blood Bonds) and a 5% chance to place 25% Decrease ATK for 2 turns with his A1. The site verdict is blunt — food: build him only if you need a warm body for Faction Wars, and prioritise Speed and survivability, nothing else.

Strengths

• The heal scales off the target's MAX HP, not his own stats, so on a fat tank Blood Bonds still puts up a real number.
• Booked, his A1 goes from 5% to 30% chance to land 25% Decrease ATK — decent for an Uncommon.
• Demons + Spirit fills a gap in a Faction Wars team against Magic affinity.
• Cheap to level and easy to feed once he has done his job.

Weaknesses

• 91 base SPD is very slow — he will heal after the damage has already landed.
• Low bases (13875 HP, 903 DEF) mean he dies fast, and a dead support does nothing.
• Single-target heal only: no cleanse, no buffs, no control anywhere in his kit.
• The Decrease ATK is only 25% and chance-based, which is not enough for serious content.

Where to use

Faction Wars only (1.5/5) — a stopgap healer for Demons until you pull something real. Everywhere else (Clan Boss, Hydra, Chimera, Arena, dungeons, Hard mode, Doom Tower) he sits at 0.5/5 and contributes nothing. Overall rating: 1.0/5.

Stats and gear

Stat priority: SPD → HP% → DEF%. Rough Faction Wars targets: 180–220 SPD, 30–40k HP, 1500+ DEF. Skip ACC entirely — a 30% chance at a 25% Decrease ATK is not worth Accuracy investment. No sets were listed in the build, so use the obvious ones: Speed (4 pieces) plus Immortal or Regeneration in the remaining slots. HP%/DEF% gloves, HP%/DEF% chest, Speed boots.

Masteries and blessings

Support tree for anything that boosts healing and cuts cooldowns, Defense tree for HP and damage reduction. Blessings are pointless here — spending them on an Uncommon is wasted, and none were recommended in the build.

Tomes

Don't. Even fully booked, his A1 is just a 30% chance at 25% Decrease ATK, and the Blood Bonds books add pocket change on top of a 10% base heal. Your tomes belong elsewhere.

Verdict

Food. Keep one copy only if you have no other way to fill a Demons Faction Wars slot, and don't sink tomes or masteries into him beyond the bare minimum.
