Concussive Blast is the first Black Powder Bomb technique. Enemies hit by the shockwave fall over, ready for an execution.
Throw into a group, then run in and finish the enemies on the ground.
You need the Black Powder Bomb unlocked first.
Blinding Dust
Smoke Bombs briefly blind enemies in the cloud, and the smoke lingers longer.
Explosive Powder
A direct Sticky Bomb hit kills the target, and the blast grows bigger and hits harder.
Explosive Shrapnel
Shrapnel raises the Black Powder Bomb's damage and blast radius.
Guarded Throw
Your own bomb blasts no longer hurt you.
