You are done with the chant.
You play the instrument with an unbelievable speed: 'con_fioco'
Your fingertips are surrounded with swirling ENERGY as you cast the spell.
The air is filled with pure energy and crackles with power.
Unseen BURSTS of magic are absorbed into the spell!
You watch with self-pride as your con fioco hits Drow venom guard.
Drow venom guard suddenly stops breathing and jerks a couple of times
violently, then falls 
to the ground, lifeless.
Drow venom guard is DEAD, R.I.P.
