Hold Em Up KT
KT, don't get ahead of yourself here:
You still haven't coughed up the dough to make the Spiderbot: please look at the post below. Time to hit up your friends and sell some equipment before entering the Cellars.
Honestly, I'm disinclined to allow a 3rd level Goodberry. Only because, if we take it to the limit, what would a 6th level Goodberry look like? Or worse, and this was a real problem when we used Fluid Priest Magic, 3rd, 4th, and 5th level Hold Person spells were disgustingly powerful.
Shape Metal is fine and makes sense for you, but casting higher circle versions of low level spells is not a house rule I want to condone. This is a fine Table Talk question though, so if you guys want to weigh in, please move it over there. In fact, I'll go there now and start it up.

In any case, damage done. I'll hold on advancing combat until a few more PCs sign in.
