In my opinion your idea is amazing, I wouldn't mind some action since it is a grave situation right now. (do or die basically) The action would come in later in the rp anyway, the only difference is that we'd probably fight better in the future after all the character development. XD
As for my weapon, thanks for informing me, but since it's like this I'll just make it so that it has a cooldown time or something similar, or maybe because Lavenza is scared hence causing her powers for the blade to be lessened. That'll be more of a challenging thing that she has to overcome, to properly control the blade with her own willpower and not only her physical abilities.
