kinda
its more like the char needs to absorb it from somewhere, acting like an elemental battery

to use smoke, he needs to find a place where there is smoke, like a chimney, drain the smoke and then he can use his powers of smoke
HOWEVER once the smoke pit is empty, he pretty much loses all power options, only drain, dash, melee, subdue and jumping abilities and passive powers till work, but no more shooting, missle, grenade, blast, abilities, nothing untill he recharges himself
and the little matter that while delsin can absorb other conduit powers, he can only use one at a time, so when he is using smoke and he drains electricity, he loses smoke, and all smoke that has been drained will be gone, so the elemental battery can only hold one element at a time.

and for the record, while he can copy other conduit powers (or I make it a drop type, though I will only gain one or two powers each arc at most, or at certain arks not even one at all), when he gets a new one, he only has dash, melee, subdue and well the basic draining powers, all the others he will need to gain and worst is, when learning a new element he cant switch to an completed one, also some elements may not even have melee and or dash, only able to drain the element, making him pretty much temporal powerless untill he can drain core relays (which I would make in a drop system, which also gets its rules and limits so it wont be like, cool i can drain fire now, ah a monkey, melee kill, cool a core reply, hey a birdy, jeej an other reply XD, no I want to take my time with making Delsin... well Delsin)
