Character Overview

ζΈΈε»δ½Ώ (Guerrilla)
Base Stats at Level 80
High-critical flame damage dealer who specializes in mark-based burst combos and strengthened ultimate mechanics. Her unique support mode system allows her to access enhanced versions of her ultimate ability, while her critical rate scaling makes her increasingly dangerous as her stats improve.

Team Composition Skill
βοΈ Combination Skill
Level: 1
Triggers when team contains 2 [Avalon (δΊη¦ι)] characters OR 2 [Flame (η°η)] characters
Effects:
- Effect 1: Self critical rate increased by 7.5%
- Effect 2: At battle start, every 15% critical rate can increase self critical damage by 7.5%, maximum 6 times (up to 45% critical damage)
Why This Matters: This team skill creates incredible critical scaling. With base 15% + Awakening 1 (15%) + team synergy (7.5%) = 37.5% critical rate, providing 15% critical damage from the scaling. Additional critical rate from runes can push this to the maximum 45% bonus, creating devastating critical strikes.
Awakening Effects

Critical rate increased by 15%
Impact: Essential for reaching critical rate thresholds for team synergy scaling
π Awakening 2 (GAME-CHANGING)

When triggering [Strengthened Must Kill], critical damage increased by 20%
Impact: Unlocks access to 1560% damage ultimate with enhanced critical damage
Awakening 3
[Skills] and [Normal Attack] level and level cap +4
Awakening 4
Must kill damage increased by 35%

Main Stat Priorities
Substat Priorities
- Critical Rate %
- Critical Damage %
- Attack %
- Penetration
- HP% / Defense%
Note: Critical rate is the most important stat due to team synergy scaling. Every 15% critical rate grants 7.5% critical damage, making it extremely valuable for maximizing damage output.
Critical Rate Targets:
- 60% Critical Rate = 30% critical damage from team synergy
- 75% Critical Rate = 37.5% critical damage from team synergy
- 90% Critical Rate = 45% critical damage from team synergy (maximum)

This memory card is perfectly designed for Merlin's single-target burst specialization.

Combined with 12% critical rate, this card provides both baseline damage and critical scaling that perfectly complements her kit.
