Conjure Oil, which does what it says

The second spell you've learned is Conjure Oil, which does pretty much what it says on the tin: it coats an object or area nearby in thick, slippery oil. Not a spell with as many immediately obvious uses in adventuring, but the crazy, one-eyed man you learned it from swore that it came in useful to him many times in his own adventures.

You're fortunate to have learned magic at all - not many people do, these days. Of course, your spells aren't the only thing you have supporting your adventuring career...
