Release1.0

Koleda Belobog is a Fire Stun Agent with some of the most explosive Daze in the game, thanks to her EX Special and her Furnace Fire enhanced Basic Attack. Her Awakened Potential turned her into a real buffer: +35% squad DMG from Furnace Fire, +35% CRIT DMG for non-Armorers and +12% Laceration DMG for Armorers. That makes her one of the few Stunners who work well with Armorers like Claret, and a strong standard pick for Fire and Rupture teams.

Teams

Recommended teams

Armorer: Claret & Rina

Claret
Koleda
Rina

Her most used team, and the ninth most used team in the current Deadly Assault. Claret activates her Additional Ability as an Armorer, gets +12% Laceration DMG from her Potential, and Rina's flat DEF buff feeds Claret's scaling. Bangboo: Ultra Jake (Claret is from Roscaelifer).

Rupture: Yixuan & Lucia

Yixuan
Koleda
Lucia

Koleda is one of the few Stunners whose Additional Ability works with Rupture Agents, and she boosts Yixuan's Chain Attacks. Bangboo: Resonaboo (two Ether Agents).

F2P Fire: Soldier 11 & Lucy

Soldier 11
Koleda
Lucy

An all-standard Fire team: everyone activates each other's Additional Abilities, Koleda's fast Stuns give Soldier 11 more burst windows, and Lucy adds long-lasting ATK buffs. Evelyn is a great upgrade for the DPS slot. Bangboo: Rocketboo (Fire).

Guide

How to play

Furnace Fire

  • She gains Furnace Fire (max 2) from her EX Special, Assist Follow-Up, Chain Attack and Ultimate.
  • With Furnace Fire, her Basic Attack becomes a two-hit enhanced Basic Attack after the 2nd hit, or by holding Basic Attack during a Dash Attack or Dodge Counter (her Assist Follow-Up, EX Special and Ultimate can themselves chain into that Dash Attack). It consumes all stacks and gives all Agents +35% DMG for 40s; each stack also raises the second hit's DMG and Daze.
  • Swap out during the first enhanced hit: she stays on the field and lands the second hit on her own.

Daze

  • Her EX Special (60 Energy) is one of the strongest Daze skills in the game, and it's faster with +10% Daze when used after the 2nd or 4th Basic hit.
  • Her Defensive Assist only costs 1 Assist Point against heavy attacks, and her Assist Follow-Up gives Furnace Fire: parry with her often.
  • Her Dodge Counter has great Daze for its speed if she has to stay on-field.

Rotation

  1. Early in the fight, parry → Assist Follow-Up → keep holding Basic Attack (Dash Attack, then enhanced Basic Attack) to start the 40s buff, then swap out.
  2. Keep Energy for EX Specials close to the Stun (and to keep King of the Summit up).
  3. Refresh the Furnace Fire buff at least every 40s; it's fine to overcap stacks if your DPS needs the field time.

Her Additional Ability (Rupture, Armorer, same Attribute or same Faction) makes each EX Special add a stack of +35% Chain Attack DMG taken on the target while it's Stunned (max 2).

Strengths

  • Some of the highest burst Daze in the game, great for fast Stuns in Shiyu Defense.
  • Unconditional squad buffs since her Potential: +35% DMG, plus CRIT DMG or Laceration DMG.
  • One of the few Stunners whose kit and Additional Ability work with Armorers and Rupture Agents.
  • Standard S-Rank that only uses 1 Assist Point per parry against heavy attacks.

Weaknesses

  • Struggles with Energy without M2.
  • Balancing Furnace Fire and field time can be awkward.
  • Her buffs are still weaker than most limited Stunners'.

Notable dupes · Mindscape Cinema

M6
Solid upgrade

Explosions from her EX Special, Chain Attack and Ultimate deal extra DMG equal to 360% of her ATK.
