Still early don't even have her weapon yet but pic related is really damn good and refunds cost and cooldown if you destroy anything when you use it the first time each turn. Like even a wine barrel and you can just use it again. Plus it's a teleport(?) not a charge or dash. Don't know how relevant disarm is for mob busting yet. Need to get into her on guard mechanic but it lets her take attacks for someone 3 tiles away and heal them.
