Currently, all temporary weapons (except needles) debuff or directly damage your opponent.
What if there were a broader range of temporary weapons that could impact yourself.
Much like an elusive magician, throwing smoke at themself to make it harder for the audience to discover them.
This will open the door for more options in things like group fighting, and create new builds dedicating to maxing out the advantage.
Some examples, but I’m sure the audience will help me modify this:
Red Smoke - Drop 25% speed, gain 100% dex
Armored Goop - Drop 50% dex, gain 200% def
Reflective Flash - Drop 25% str, gain 100% speed;
Metal Spikes - Guaranteed opponent non-stealth
Gas Spill - Gain 25% Speed and Dexterity, 40% extra damage received from flamethrower and incenderary ammo
Portable Fan - Remove Smoke effects
Sticky Icky Bubble Tar - Gain 10% Critical Hit and Damage, but drops Dexterity and Speed by 25%
Protein Rage - For 2 turns weapon can hit everyone in the group attack with 50% extra damage but drops your str and speed by 50% in the next 3 turns
