Energy Siphon

This spell needs 2 targets, both within 60 feet of you. Yourself can be either of the targets. The drain target must make a Wisdom saving throw unless specified otherwise, or suffer the effects of the spell. Reroll the save at the end of the creature's turn. You can do a few things:

1. Reduce a creature's movement speed by 15ft, and increase another creature's movement speed by 15 ft. (+5ft/spell level, target cannot be left with less that 5ft of movement)

2. Reduce a creature's ability score by 2 (saving throws and ability checks), and buff the same ability score of another creature by 2. The save is made with the ability score in question. (+1 per every 2 spell levels up cast)

3. Reduce a creature's damage rolls by 1d4, and increase another creature's damage rolls by 1d4. (Progress through D6>D8>D10>D12 per every 2 spell levels upcast)
