Overview

Rosetta is one of Wind's premier buffers, but only for Solo play. Any form of Blind or Charm will severely limit her abilities, nearly making it impossible to make use of her Rose Barrier stacks. When these things aren't an issue, though, she is an incredible buffer that will carry you through High Level content, with a near-permanent up time on her buffs when there is at least one good source of Double/Triple Attack or charge bar generation. Note: Due to Rosetta's unique play style that requires her being hit (i.e. take damage) to gain stacks of Rose Barrier, she has terrible synergy with Niyon, and any unit that provides a blind, charm, or any status effect that stops the boss from attacking.

How to Play

With Rallying Gong Crew Buff;

1. Activate Rose Barrier at 30%.
2. Raise Rose Barrier stacks up to 4.
3. Use Iron Maiden to raise the Rose Barrier Stacks to five.
4. Press Rose barrier to activate the buffs.
5. Repeat

Synergy

As Rosetta is a character primarily used for Solo play, she has really good Synergy with both 5★ Lennah, who clears buffs easily, but more importantly, she has amazing synergy with Jeanne d'Arc (Summer), as her Salvation Ability reduces the damage Rosetta takes even further, which is especially important in High Level content where Rose Barriers defense bonus starts to mean less and less. Aside from that, Rosetta is a great fit for any solo team when Niyon is not 5★ (or when her Comatose skill doesn't work).
