Drop the scary illusion, and try to simultaneously replace it with something like a blur spell. Something to make me less identifiable. Then skedaddle away and try to hide. If the wall around this tavern is easily climbable, I go over the wall and circle behind the tavern, before climbing back in.
Regardless of where I end the turn, check my magic reserves.
You drop the illusion and draw up an illusion to make you hazy and indistinct, then climb to the top of the gate. looking out, the street is full of people. several fights have broken out, and the alleys are full of people making discrete transactions. One guy is clubbing something just out of your sight, and several others are cheering him on. Could be a fun trip around the inn. Your reserves are fine.
Scan the crowd for impertinent looks. Discipline appropriately.
You look around at all the stunned faces. How rude. You decide to show them. You turn back around, bend over, and slap your ass. "Suck it, drunkies!" You shout, shaking your fleshy parts at them. After a moment, someone laughs, and someone else applauds. The quiet in the courtyard is replaced with the general murmur of people getting hammered again.
Hide near the gate and spit venom at anyone dumb enough to climb it.
-looks at syvarris' action- Ah the comedic potential here.
But no, someone from outside actually does try to climb the gate. several someones, actually. They fall back into the crowds outside, screaming, with venom in their eyes.
