Update: Rise My Minions! - Version 1.5.0 for Minecraft 1.6.4
A new minion summoning system has been implemented! Press H to open the Minion Manager. You'll need to craft a Soulgazer and use it on mobs to learn how to summon them, not every mob can be summoned though. You'll then need a Summon Staff, by pressing and holding R you can choose which minion set you want to use.
Added advanced pet controls for both Minions and Pets, right clicking on a pet or minion will open the Pet/Minion GUI.
Fixed a crashing bug with custom Potion Effects (Weight and Paralysis).
