Brewing in the Deep

The Deep has no nether, so how are you supposed to brew potions without blaze rods or nether warts?

You can't. Luckily, McMMO fishing has a chances for the player to fish up blaze rods, so you'll have to use fishing if you want the real ultimate potion power. Using a special sign, you can trade one of your blaze rods for a nether wart at the trade nexus of /warp deep. Find soul sand by excavating sand (another McMMO rare drop) and your alchemy apocalypse can begin.

So that's it. Just start fishing!
