I'm up to no good and I could use a fireball out of the blue. Problem is - I'll probably not be having my partys spellcaster nearby when on the job and it's quite likely he won't have to level to cast one anyway..not to mention I'm not sure if any of them actually CAN do that.
I do know however that at least one of them will be taking Craft Wonderous Item and there's a good chance I'll be able to borrow an npcs wand, use it and put it back before anyone notices I've been doing something I shouldn't.
Now our resources will be limited, so I'm looking for the cheapest way to get a spell storing item. So far best I found was a ring costing 9k to make (+scroll cost for Imbue with spell ability)..quite a bit and it's a ring, but maybe we can craft something with the same functionality.
Any cheaper options? It's fine enough even if the item in question would be one use (funnier even if I can do that with bird feed or a similar dastardly thing ot just leave behind for someone else to activate by accident)
While I could second the note which says "I prepared explosive runes today" a level 3 druid casting fire trap is cheaper, albeit the spell does only 1d4+3 damage versus the 6d6 of explosive runes. You could also use the trap rules to create a trap, but a trap would likely be more expensive than fire trap/explosive runes/symbol of death spells (well not symbol of death).
