Accidents do often happen ...even to the warforged....
I'm just waiting to clarify if we have horses and how many and we can begin day two of the hike. The deeper we go into the mountains and forest the more likely things can happen randomly.
You could always do a spellthief. We could use some soft of magical/ranged offense, since we have only a cleric as far as spellcasters go. Or an Arcane trickster (Well, aiming for it). But whatever you want works.
