Timing

Open with Battle Skill to apply Heat Inflictions and Vulnerable. Use Combo Skill after Heat Inflictions is applied for Perfect Timing bonus. Deploy Ultimate before burst windows for team Haste + ATK%. Use second Combo Skill to consume all stacks for massive damage. Leave enemy with 3 Vulnerable stacks for teammates to consume.

Quick Reference
Min-Max Tips
1.

MI Security requires <49.4% UGE (or <56.4% with Gilberta buff) - adjust gear pieces to maintain breakpoint

2.

Critical Rate cap is 56.5% - prioritize reaching this before Critical DMG

3.

Perfect Timing Combo Skill requires Heat Inflictions OR Heat Inflictions on enemy - coordinate with Wulfgard for Heat/Combustion

4.

Lupine Scarlet provides ~20-25% more damage than P5 Glorious Memory - highest priority pull for Rossi mains

5.

Rossi applies Vulnerable through Battle Skill vs marked enemies - mark requires Vulnerable first (chicken-egg)

6.

Ultimate provides team-wide Haste + ATK% - position Rossi near DPS for maximum buff uptime

7.

Rossi is P0 viable - core mechanics work without any promotions

8.

Team order matters - position Vulnerable consumers (Endministrator/Pog) after Rossi for stack consumption
