Bee-line: Shoots a yellow sphere that explodes with a radius similar to a large shot. This weapon deals about 45 damage, and does not arc. Once fired it continues on a straight path until it collides with something or goes off screen. It’s trail could alternate between yellow and black.
Deluge: Similar to the “Rain” skill, the main difference is that this weapon is worth using. Each drop deals 6 or 7 damage. Perhaps add this in a weapon pack?
Storm cell: A “call-in” that launches a blue sphere with a yellow core. Lightning strikes twice where it lands, first a little to the left for 20 damage, then to the right for 20 damage once more. If it lands on or very close to a target, the target takes damage from both bolts. Rain will fall while the lightning strikes, dealing 6 damage per drop in the designated area.
