idk. common, uncommon, rare, epic, unique. 3 x 3 x 3 x 3 x 3 = 243...... im so confused...
Oh, wait. theres also exceptional....
exceptional? I don't think i remember that tier, what upgrades are in exceptional?
Acid, Burn, Homing, etc.
wait, i think i said epic before. i think that epic and exceptional are the same tier
Grey, yellow, red, blue, green.
Common, uncommon, rare, exceptional, unique.
ok, so 5 tiers, 4 to get from common to unique, 3^4=81. So it is 81
