Unbound Potential

While wearing The Unleashed, Hit enemies with Spells to gain Runic Bindings, no more than once every 0.5 seconds. Shapeshifting while you have Bindings removes all of them and grants the same number of Unbound Potential stacks. Each stack grants 20% increased Damage, 10% increased Armour, and 10% increased Energy Shield. The maximum is 10 stacks, one stack is lost every 5 seconds, and returning to Human form removes every remaining stack.

The Unleashed is the source

Unbound Potential is not a general Shapeshift reward. It comes from the unique Revered Vestments named The Unleashed. The item is obtained by Runeforging Revered Starlit Ore and cannot be obtained through ordinary random drops or an Orb of Chance.

Spell Hits build Runic Bindings

The Unleashed grants 1 Runic Binding when you Hit with a Spell, limited to once every 0.5 seconds. Damage over time without a Hit does not satisfy that wording. Runic Bindings cannot be gained while Shapeshifted, so the setup phase takes place in Human form.

Bindings impose a temporary cost

Each Runic Binding gives 10% reduced Spell Damage and 2% reduced Skill cost Efficiency. You can hold up to 10, and they last 10 seconds. At 10 stacks the listed penalties total 100% reduced Spell Damage and 20% reduced Skill cost Efficiency before other applicable modifiers are combined.

Shapeshifting converts every Binding

When you Shapeshift with The Unleashed equipped, all current Runic Bindings are removed and you gain the same number of Unbound Potential stacks. Five Bindings become five Potential; the conversion does not automatically fill the buff to its 10-stack maximum.

Each Potential stack has three bonuses

One Unbound Potential grants 20% increased Damage, 10% increased Armour, and 10% increased Energy Shield. At the maximum of 10, those listed bonuses total 200% increased Damage, 100% increased Armour, and 100% increased Energy Shield. Increased Damage is additive with other applicable increased Damage modifiers, not a 20% more multiplier per stack.

Stacks decay instead of sharing a duration

You lose one Unbound Potential every 5 seconds. The mechanic does not describe every stack expiring together after 5 seconds. Starting from 10 stacks, the full set takes 50 seconds to decay if you stay shapeshifted and no other rule removes it.

Returning to Human removes the buff

Shapeshifting into Human form removes all remaining Unbound Potential immediately. The usual cycle is therefore to build Runic Bindings as a Human, enter an animal form to convert them, use the bonuses while they decay, then rebuild after returning to Human form.

Unbound Potential is not Unbound Fury

Unbound Potential belongs to The Unleashed and the Shapeshift system. Unbound Fury is the separate resource used by the Invoker skill Unbound Avatar. The similar names do not make their stacks, limits, bonuses, or activation rules interchangeable.
