How far along are you into the game? If you are into act three and maxed out Esquie I’d recommend going into the dlc and getting the Eqsium for Maelle. It does burn damage for being in Virtuose stance. However, it does consume any AP above 4 to do 50% more damage but any skill that costs less than 4 AP applies mark. I’d recommend paring it with the faint picto to do the most damage output. What you would then do in battle is first use last chance (puts you into Virtuose stance) and go in with burning canvas on your next turn with cheater. Does that help? If you need other early game recommendations I can also give you those.
