Transfigure is an ultimate constitution ability. It binds the user for 6 seconds, and when the bind ends, the player heals 250% of any damage taken during the stun, and becomes immune to stuns and binds for 15 seconds.
Despite the description, the maximum amount of life points restored using this ability is 5,000, making the optimal damage taken 2,000. The ability cannot be used whilst immune to stuns, and Freedom is disabled while under its effect. Transfigure takes into account all incoming damage, including typeless damage from various attacks and self-inflicted attacks from abilities like Blood Tendrils, and even damage from dropping Nitroglycerin. It is still possible to die while the effect is in place. The stun administered by transfigure is not a true stun, meaning it is still possible to eat and change prayers under its effect.
You can also obtain Transfigure, as well as the Devotion and the Sacrifice ability easily through killing the followers of Armadyl and Bandos in their respective encampments in the God Wars Dungeon, such as Aviansies. To obtain the abilities Lootshare should be Enabled. These abilities are individual drops, however you may receive multiple abilities in a single kill.
When received as a drop from either the Generals or the followers, it is automatically learned; it does not drop as an item. When received as a drop, the message "You have unlocked the Transfigure ability!" appears in the chatbox.
