[3.5] How would you stat this dwarf ale canon for D&D?

[Pika...]

I am dying to use these models in D&D, especially in my current semi-campaign, but I have no clue how to stat them.






The very basic concept I am think is that they reinforce one very big barrel, then have to refill it with very well fermented Dwarven ale for the next "shot" (whatever kind of shot that would be).

Heavily fermented Dwarven ale has become a common joke in both my campaign so far (this is campaign #3, but with the same group as #2) without me even causing it, so I am looking to have some fun with this. ^_^

One of my DM sayings is 'Never give the DM ideas, because he just might use them.", and boy it would be true right now.

Fires in a 30' Cone
Full round action to fire.
Rotating cannon 45 deg costs 5' of movement.
2 x full round actions to reload.
Characters cought in blast must make DC 15 fortitude save or take d6 Wis, d4 Int, d3 Cha and d3 Dex damage (recovers overnight), be sickend for 1 hour and confused for 1 round. 1 Wis damage even on a successful save.

That is if it fires normal liquid....

If it is on fire at the time, replace all damage/effects with about 10d6 fire, Reflex half in the same area.
