Alright looking it over now.
EDIT
Having given it the quick once over I am wondering about the acid damage. Given the rate at which it can be used have you considered lowering it to 2d10? If it had a longer cool-down time I would say the 2d20 could certainly work.
Also you need to separate the description from the combat section, and switch 1-3 to 1d3 for the number encountered. Other than that the formatting looks good.
