[@Seirei No Hai] I like her. I don't have any problems with her backstory and such.

Although abilities... Well let's see.

Combat Amateur might need to be changed, since crits are normally tied to builds and abilities instead, and that there is no weapon durability. This honestly seems more like an Opportunity skill instead. You can start with 3 like everyone else, as Valdr's opportunity skill are tied to story progression.

So you may need to rethink that skill. I think you should change it out for Dualcast or Tricast (with a specification).

Ifrit's Essence though will do something else. All fire magic up to Firaga can be used without the drawbacks of using a spell stronger than your stats, but only while you have the amulet. Even with that drawback of needing the item, this is still really powerful, so remove the tricast from it and move it someplace else.

Furthermore, Limit Break has changed in how it works, you may want to review that. Your spells are such are fine, but tier 1 spells like Fire, Blizzard, etc. would actually be valued at 3.
