Mirror Image question

I did a search and couldn’t find an exact answer here. How does a mirror image damage stack? (is it different in PVP?) Does it have the same chance of doing exact damage as your character? Or if there are 2-3 mirror images, is the DPS split?

Mirror images are summoned units that deals its own separate DPS. Its DMG depends on your OH.

Oh I see…thank you for clarifying that.

Stupid question but does leveling up actually increase anything beside give you stat points?

A pop up appears every time you level up. It tells you that you gain HP, MP and stats.
