Rosaria's Core Mechanics: Agitation & Inferno Stacks
At first, her kit might feel like just another DPS, but once you understand how her stacks work, everything clicks. She’s all about building momentum early, then cashing it in for huge burst damage. If you’re following a proper Star Savior Rosaria build, mastering these mechanics is what really separates average damage from insane carry potential.
Key Mechanics:
- Agitation Stacks:
You build these constantly through your skills. Think of this as your setup phase.
- Inferno Stacks (Undispellable):
These are your real powers. The more you have, the harder your Special hits.
- Stack Synergy:
More Agitation increases your chance to gain Inferno. So you’re always building toward bigger damage.
- Burst Cycle:
You stack first, then use your Special to unleash boosted damage based on Inferno.
- Passive Safety Net:
When things go bad, she won’t drop below 40% HP once and gets a big ATK boost — perfect for clutch moments.
Skills Breakdown
Each of Rosaria’s skill does something important: some build her power, some deal big damage, and some help you control the fight or stay alive. If you learn how to use them right, your Star Savior Rosaria build will feel smooth, strong, and just plain fun to play.
Here’s a breakdown of Rosaria’s skills:
|
Skill |
What It Does |
|---|---|
|
Basic – Ashen Inferno |
Deals single-target damage and builds Inferno stacks. This is your bread-and-butter to keep your rotation flowing. |
|
Special – Ruler’s Judgment |
Heavy single-target burst that scales with Inferno stacks. Timing this correctly is key for massive damage. |
|
Ultimate – Difference in Class |
AoE attack that applies DEF Down, boosts Action Gauge, and generates Inferno stacks. Use it to kick off combos. |
|
Passive – Tyrant of the North |
Increases Inferno gain based on Agitation stacks, prevents death once (HP stays at 40%), and gives an ATK boost. The ultimate safety net and power spike. |
