how can you use doge rolling?

[MochiGem]

Hi @EvilDragonfiend! The Dodge Roll action automatically appears in the mob's Action Panel / Action Bar. Clicking the 'Dodge Roll' action button triggers a directional roll with a 0.6-second invulnerability window and a short cooldown.

This will remove god mode if you already have it. Fix that.

[MochiGem]

Good catch @EvilDragonfiend! I have updated the implementation to check was_already_godmode prior to rolling, ensuring pre-existing GODMODE states (such as admin invulnerability) are fully preserved when the roll completes.
