I find it very strange that you can upgrade a trinket and then have to wait a long time before you can finally use it, whereas you can have literally just used a bilgewater cutlass and then upgrade it and the botrk will not be on cooldown. Why is this?
Crett1 votestrinkets are a special case.
in other item's cases, that's all unique passives.
you can buy all three of these 
and blow their actives willy nilly, because they don't share cooldowns.
Miku Lv991 votesI understand that. But why did they make trinkets work differently than those other items? Would upgrading them have been too op if they always came out off cooldown or something?
