Healing Incense is the second Smoke Bomb technique. Standing in your own smoke restores some health, so a Smoke Bomb doubles as a heal.
Throw smoke when you are low to break line of sight and recover at the same time.
You need Blinding Dust first.
Blinding Dust
Smoke Bombs briefly blind enemies in the cloud, and the smoke lingers longer.
Concussive Blast
The Black Powder Bomb's shockwave knocks enemies down.
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.
