launch bolt + eschew materials
launch bolt launches any light crossbow bolt with a range increment of 80 ft.
eschew materials ignores the cost of any material under 1g.
a bolt costs 1 silver.
+1 size catagory to it doubles the cost.
a gargantuan light crossbow bolt costs 8 silver and does 3d6 damage.
launch bolt never said anything about "size appropriate" light crossbow bolts.
incidentally, casting launch bolt as an SLA means you can do it with collosal bolts. and yes, I know about the warmage edge abuse, and the fel draining acid splash. this post is for entertainment purposes only. also, arcane thesis(launch bolt) anyone?
