If you have two or more similar stackable items and chest, you can clone them:
1) Put one item in chest.
2) Put second item in chest. In result you have two stocks: first with one item and other with two.
If you close chest stock with one item will disappear, but if you grab it in your inventory it won't disappear.
3) Put this item in chest again. In result you have 3+1 items.
4) Grab&put it again to get 4+1 items etc.
Also I noticed, that flaming hands hits only 8 squares. Creatures, who stands on ninth square don't receive any damage.
Thanks, I'll check these out.
