Fearsome Blast
Source
Starfinder Enhanced pg. 40
You maximize the chaos caused by a mid-combat explosion. When you activate or attack with a grenade, you can use this improvisation to spread fear among anyone caught in the grenade’s area of effect. Each creature affected by the grenade must attempt a Will saving throw, in addition to saves against the grenade’s usual effects. This save DC equals either 10 + 1/2 your envoy level + your Charisma modifier, or the grenade’s saving throw DC + 2, whichever is lower. A creature who fails the saving throw is shaken for 1d4 rounds. A creature whose Will save result is a natural 1 is instead frightened for 1 round, after which they are shaken for 1 round. Once you use this improvisation, you cannot do so again until you take a 10-minute rest to recover Stamina Points. This is a fear effect.
