Caliban doesn't use mana but can hold a several gadgets (displayed on his resource bar similar to Rengar's ferocity bar). He has three different kinds of Gadgets, however they are not displayed on the resource bar and are not visible as buffs. They appear as ammo similar to Corki's Missile Barrage.

I suggest you read his stance ability (Ultimate) before reading the rest of his abilities.
