since your pack is so awesome already, i'm not even going to pretend i can help with the design or theme. So i thought about it, and i came up with some stats for weapons.
-30% airblast cost
-10% primary ammo
airblast can rapid fire
stream of fire is thinner
Longer melee range
+35% attack speed
Is it okay to call it the "horticultural horror" pack?
-20% damage from environmental sources
