Binding Rockets

2nd-level engineering 

Pulling Time: 1 action

Range: 300 feet

Duration: up to 1 minute (6 rounds)

Choose one creature you can see within range. You release black seeker rockets that target your foe and after impact release a black goo that binds the target in place. The target must succeed on a Strength saving throw or its flying speed (if any) is reduced to 0 feet for the gambits duration. An airborne creature affected by this gambit safely descends at 60 feet per round until it reaches the ground or the gambit ends.
