Oh okay hmm the flames wouldn't destroy anything it instantly touches. It would be able to add extra damage to something like if someone hit a metal door he would be able to weaken the door even further or weaken it enough to knock it down.

If he manages to get the wires around someone he can use the flames to give a slow, continuous burn weakening the person long enough for someone to either take them away or knock them out.

When he has the full power of his Flames he will be able to focus on anything in his range and add extra damage to it, to the point where it can be easily destroyed by someone else. The Flames at full power will only be able to reach as far as his wires can reach and only be concentrated in that one spot, not all over.

I'm aiming for his flames to cause extra damage to a buildings and objects. For people it would weaken them, but if they were strong enough they could overcome it then break out of his hold.

Is that alright? Or should I change it up a bit more?
