Thunderstruck

this is a bardic spell that summons 1-10 lightning bolts from the sky on anyone that you can see.

you get 10d10 to share among 1-10 entities that you can see.

you can choose how many d10s go to what entities. for example, if there are 5 enemies, you can put 2d10 on all of them, or you can put 6d10 on one enemy and put 1d10 on the rest

if there are 10 enemies you hit with this spell, you get advantage on the hit/attack roll.

if there is 10 enemies or less, you have to hit every enemy with at least 1d10 of damage. if there is more than 10 enemies, then you can choose which enemies to target, but you still have to hit the maximum targets you can.
