Let's nerf 2 spells

Heat Metal and Summon Insects are too powerful. Unconscious for 10-40 rounds?? How about we change it so that if it's a weapon, save v. spell or drop it (lose 1/2 of your attacks per round to pick it back up, can't reduce to 0). If it's armor, lowers AC by 2 (since its melted).

Summon Insects, how about you take 1 round to fend them off and then it gives -2 to hit for melee & ranged, and if you are casting, make an Int or Wis check to not lose spell?
