This is a build designed to farm keys fast, while be very easy to play. In my opinion, this is the fastest key farming build for Wizards, and maybe even for all classes.
This build has high mobility with double Teleports without cooldown. There is no need to cast a signature spell and resource is not a problem. An entire screen of trash mobs gets pulled in with autocasted twisters. Trash will die to a single twister that can be casted at range. Unlike other speed key farm builds, this build doesn't rely on killing elites for Ingeom buff.
Simply teleport around and tap the beam to pull in trash. Keep moving because trash will die from the twister. You should only need to hold beam for a second to kill elites.
If trash is not dying from a single twister, you may benefit from lowering the Torment Level. Torment 10 still drops 2 keys, while Torment 13 only has an additional 25% chance to drop a 3rd key, while increasing monster health by more than 4x. If you can clear Torment 10 faster, this may result in more keys per hour. With optimal gear and a decent Paragon, Torment 13 should be done just fine.
If this build helps you, please give it an upvote. I appreciate the help!
