Summoners War: Water Ciri and Racuni Siege Offense Guide

Pair Water Ciri (or her non-collab counterpart, Water Birgitta) with Racuni to eliminate Critical Rate rune requirements and establish a low-RNG offense for Guild Siege. Because Water Ciri lands guaranteed critical hits on her attacks, you can allocate all offensive rune stats into Attack, Critical Damage, and Speed while using Racuni to repeatedly boost her Attack Bar, cleanse debuffs, and cycle turns.

Water Ciri Stat Priorities and Rune Sets

Water Ciri does not need Critical Rate substats or a Slot 4 Critical Rate rune. Keep her Critical Rate at the base 15% and allocate every offensive roll into Attack, Critical Damage, and Speed, backed by enough effective HP and Defense to survive stray hits.

Stat	Target Benchmark	Primary Function
Speed (SPD)	+110 to +140	Keeps pace naturally between Racuni Attack Bar boosts
Critical Damage (CD)	150% to 180%+	Scales damage on Slot 4 without requiring Critical Rate
Attack (ATK%)	+1,200 to +1,600	Delivers base scaling for Skill 1 and Skill 2 burst
HP & Defense	+12,000 HP / +400 DEF	Protects against neutral single-target hits
Critical Rate (CR)	Base (15%)	Bypassed entirely due to guaranteed critical hit mechanics

Recommended Rune Sets

Violent / Will: The standard build. Violent procs let Ciri rapidly reuse Skill 2 (which strips beneficial effects and stuns across two hits), while Will protects her against opening debuffs.
Violent / Destroy: Recommended against heavy sustain monsters like Camilla or Ariel. Destroy runes reduce maximum enemy HP with each turn cycle, preventing defense teams from out-healing Ciri's output.
Violent / Nemesis: An alternative offset to interrupt enemy turn flow if Ciri takes incidental area-of-effect damage.

Racuni Speed Tuning and Mechanics

Racuni acts as the engine for this team by funneling turns into Water Ciri:

Attack Bar Maximization: Racuni's second skill, Rabbit's Agility, fills an ally's Attack Bar to maximum and grants a two-turn Speed buff. Speed tune Racuni to move right after Ciri takes a natural turn so she can attack twice in rapid succession.
Passive Cleanse and Healing: At the start of Racuni's turn, his passive cleanses harmful effects and heals the ally with the lowest HP percentage. This ability does not check Accuracy or Resistance, letting him clear defense breaks off Ciri automatically.
Runes and Stats: Build Racuni on Swift/Will or Violent/Nemesis with high Speed and maximum effective HP. Aim for 100% Resistance on Racuni so enemy crowd control cannot interrupt his cleanse loop.

Selecting the Third Monster

Water Ciri and Racuni function as a self-sufficient duo, leaving the third slot open to counter the enemy's elemental threats or support Ciri's setup:

Wind Tanks (Feng Yan, Taranys, Xing Zhe): Absorb attacks from Fire snipers and Water bruisers, keeping enemy focus away from Racuni and Ciri.
Support Buffers (Woosa, Riley): Provide immunity, shields, or Attack buffs to increase Ciri's damage output while guarding against heavy area-of-effect skills.
Secondary Strippers and Bruisers (Aegir, Miles): Provide additional strip pressure and Attack Bar pushback to shut down a priority target.

Do not bring a primary damage dealer who requires Racuni's Rabbit's Agility to function. The composition works by funneling every turn boost directly into Water Ciri so she can maintain stuns and Attack Bar absorption.

Matchup Selection

Deploy this offense into predictable, sustain-oriented defense teams:

Favorable Targets: Slow bruiser defenses, reviver teams, and single-threat compositions (such as Carcano or Aegir defenses). These teams lack the burst damage required to break through Racuni's passive healing before Ciri strips shields, lands stuns, and destroys maximum HP.
Hazards to Avoid: High-speed cleave defenses and ignore-defense snipers (such as Sonia, Covenant, or Kahli). If an enemy unit can eliminate Racuni or Ciri on turn one before Racuni moves, the engine fails immediately.
