Ok, how is this:
"Weapon (Ranged): Deals damage based on psi level.
![Air :air](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/air18x18.png)
Pump: Increase psi by 1, reusable. Lose 1 psi per turn"
Then I can set the formula to scale damage similar to catapult.
Maybe have it max out at around 15 to 20 damage to keep pace with farenheight?
