Got Your Back

Interstellar Species pg. 22
As a move action, you grant the unflankable universal creature rule to yourself and a number of creatures that doesn’t exceed your Charisma modifier. When you use this improvisation, each creature affected must be within the melee reach of at least one other affected creature. The effect ends for an affected creature if it ends its turn without being in the melee reach of an affected ally. This effect lasts until the end of your next turn. If you spend a Resolve Point when activating the improvisation, it instead lasts a number of rounds equal to your Charisma modifier.
