Firewall fires a directed wall of thermite towards the enemies' direction. After a brief activation time, Scorch will slam his arm to the ground, causing a direct line of thermite to shoot out. The line will go towards the direction Scorch was looking at time of activation. If the line hits anything solid, including Tone'sParticle Wall, it will stop. This ability can be used to trigger Incendiary Traps.
If anything human-sized is in the line, they will sustain major damage. If the human-sized enemy stays in the wall for 1-ish seconds, they will die. The Scorch kit Fuel For The Fire will allow the firewall to be activated 2 seconds early. The initial activation (The wall traveling forward) does not do any extra damage.
