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, although this immunity does not appear on the Buffs and debuffs bar. The healing is capped at 75% of your maximum lifepoints, taking armour and bonfire boosts into account.
The ability cannot be used whilst immune to stuns. Freedom (along with all other abilities) 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. Transfigure's bind only disables abilities and movement, meaning that it is still possible to eat and change prayers under its effect.
If fighting Kree'arra or General Graardor for these abilities, it is highly recommended to have LootShare enabled, as they seem to be dropped much more quickly with LootShare on compared to not having it enabled.
These abilities are individual drops, however it is possible to receive multiple abilities in a single kill. When received as a drop it is automatically learned; it does not drop as an item. When learned, the message "You have unlocked the Transfigure ability!" appears in the chatbox.
Originally, the healing was capped at 5,000. After an update on 22 August 2016, this cap was changed to be 32,000. Finally, on the 12 September 2016, the healing cap was changed to be 75% of the user's maximum life points.
