How to regain drained stats?

[grrraaaa]

While stomping on Fidac's many undead, my character got a little stomped upon himself. A beefy 8 Con has been drained down to an embarrassing 3. Needless to say, I don't want to expose my 171 hit points to a level 12 dungeon.

So: where's the cheapest place I can get my stats restored?

You can buy a potion at the temple store. (Store "4")

You can also use the spell Restore Stats.

I actually went north of Fidac and found a store selling Lilly-things. Got a restoration one cheap!
