Attack1454 Guide: Thylessia
In short
Thylessia is an Epic Force Attack champion from Knights Revenant. She excels at applying AoE Decrease DEF 60% and extending debuffs, while her passive places Hex and can spread debuffs when combined. Her best role is in Faction Wars, where all her abilities shine. Build her as a priority for faction crypts.
Strengths
- AoE 60% Decrease DEF for 2 turns with decent damage — a foundation for melting waves.
- Extends all enemy debuffs by 1 turn with her A2, enabling strong control and debuff upkeep.
- Passive applies Hex when attacking Decrease DEF targets, setting up A1 to transfer a random debuff to all enemies under Hex.
- Good AoE multipliers and solid base ATK for an epic.
- Low book requirement — only A3 and A1 are critical.
Weaknesses
- Low base SPD (97) demands heavy speed investment in gear.
- Requies setup: first Decrease DEF, then passive Hex proc, then using A1 — unreliable without speed tuning.
- A1 debuff spread chance caps at 70% even when booked, leaving it inconsistent.
- Squishy — dies easily without healing or protection.
Where to use
Faction Wars (4.0) — ideal for wave clearing, extending debuffs, and AoE DEF down. Dungeons (3.0) — speeds up trash waves up to mid stages. Arena (3.0) — usable as a nuker-debuffer in early teams. Clan Boss (3.0) and Hydra (3.0) — viable at lower difficulties. Chimera (2.5), Doom Tower (2.5), Hard Dungeons (2.0) — falls off due to speed and survivability demands.
Stats and gear
Stat priority: SPD ~200+ (aim for 220+), ACC ~200-250 (content-dependent), then C.RATE to 100%, C.DMG, ATK%. Recommended sets: Speed, Perception, Accuracy for stat needs; Savage for damage. Relics: Malefic Talon (ignore DEF) and Irethi Coront (skill cooldown reduction on kills) are excellent.
Masteries and blessings
For PVE dungeons, CB, Doom Tower, FW, use Offense and Support trees leaning towards debuff extension and damage. T6 mastery choices: Pierce Defenses (general ignore DEF) or Boss Slayer (extra damage vs bosses). For PVP arena, go Offense and Defense trees for a resilient nuker. Blessings: Phantom Touch boosts damage, Cruelty improves debuff landing on Hex.
Tomes
Prioritize Melancholy (A3) first — the -1 cooldown lets you apply Decrease DEF far more often. Then max Madness Fog (A1) for the 70% spread chance. Harh Voices (A2) can be left unbooked as it only gains damage.
Verdict
A reliable epic debuffer-nuker for Faction Wars and early-to-mid dungeons. While not top-tier elsewhere, the AoE 60% Decrease DEF and debuff extension make her a solid investment for clearing faction crypt.
