ON THIS WIKI
Instilled Loyalty is a Mob Infusion added by the Thaumic Horizons mod. It can be applied to any creature except Spider, Cave Spider, Silverfish, Slime and Magma Cube. The resulting creature will not attack the player, but will instead attack the player's enemies as if it was a tamed Wolf. The creature can be told to stay on one place by right-clicking it. Right-clicking again undoes this order.
Thaumcraft 4 Research Notes
You will obey!
"You have discovered a method of harnessing wild beasts for your own purposes. The Instilled Loyalty infusion forcibly rewrites portions of the subject's mind, removing any hostility it may have held toward you and replacing it with a fierce dedication to its adoptive "parent."
Creatures subjected to this process will defend you much like a tamed wolf, even if they originally had no aggressive instincts. They can be commanded to remain still by right-clicking.
This infusion cannot be applied to creatures with particularly primitive nervous systems - spiders, squids, slimes, and the like.
It should be noted that certain creatures may lose abilities when their minds are rewritten - for example, creepers will forget how to explode.."
