Monster Domestication Guide is an unlockable active item in Fiend Folio: RELOADED, a mod for The Binding of Isaac.
Permanently charms the nearest non-boss enemy and ensnares it to Isaac.
Since the enemy is ensnared, it can only move a short distance from Isaac.
Once the enemy is killed, the item will be recharged. It cannot be recharged via clearing rooms or picking up batteries.
The item's charge will not be depleted if no valid enemy was nearby when used.
When Isaac heals via any manner, the ensnared enemy's HP will be fully restored.
Defeat ???, The Lamb, Mega Satan, Mother, The Beast, Delirium, or Ultra Greedier in Fiend Folio as Tainted Jacob.
