This places a poisonous cloud in a neighboring square.
A truly ferocious spell. You begin by spitting at a chosen foe. As the spittle flies from your mouth, it transforms into a venomous ball of green poison. If it successfully strikes your foe, it will explode into a cloud of choking poisonous fumes. These will linger long after your foe has succumbed, killing mercilessly any who stray within.
