Go for it. Marius will pocket the arrowheads and one machete.You should take the shield too, if Tazmara does not claim it. Now that we have found a smitty and supplies, Marius would really like to learn Craft (Blacksmithing). I was unsure what to go for in the mid to late game, but crafting armor and eventual magical armor (Master Craftsman and Craft Magic Armor) would be a decent idea.

Just tell me ahead of time if we have the downtime to actually use these feats.
