Sticks to snakes

This spell turns 2d8 sticks into snakes. There must, of course, be sticks or similar pieces of wood (such as torches, spears, etc.) to turn into snakes. Such a stick cannot be larger than a staff. The snakes obey the Caster's commands but will turn into sticks when slain, when the spell's duration ends or if the caster orders the snakes to turn back into sticks. 
The snakes may be poisonous, roll 1d6 for each snake; on a roll of 1-3, the snake is poisonous. For every snake, you add +3 poison damage per turn for the duration of the spell

Snakes AC-12, HP-1, Attack Bonus +4
Bite-1d4 per snake (+3 if Poisoned)
