 * slain x4

Description
When I trained as a Brewmaster, I didn't expect to use my knowledge like this...

Did you know beer catches fire when lit? Well, with yaungol oil mixed in, it's downright explosive.

I've mixed the oil in with these kegs. Roll them at the yaungol over by the gate, and ignite them when you get close.

It'll take a few seconds for the keg to blow, but when it does...

Well, let's just say I wouldn't want to be over there.

Which is why I'll be over here. Mourning the loss of this brew.

Progress
Wha? I was just thinking about my poor, poor beer...

Completion
Whoo, that was an explosion! Several, in fact.

Sad my beer had to go, but at least we're safe, for now.
