[[File:Imbued heart detail.png|left|150px]]
The '''imbued heart''' is a magic-boosting item dropped by [[superior slayer monster]]s, which are rare encounters unlocked after purchasing the unlock ''Bigger and Badder'' for 150 [[Slayer reward point]]s from any [[Slayer master]].

Players can use the ''Invigorate'' option on the heart to temporarily increase their [[Magic]] level by 1 + 10% of the player's level, rounded down. It can be activated an infinite number of times, but it can only be activated once every seven minutes per player, regardless of how many imbued hearts are owned. Attempting to use the ''Invigorate'' option while it is on cooldown will result in the chatbox message ''The heart is still drained of its power. Judging by how it feels, it will be ready in around X minutes.''

The cooldown resets on death, even in safe minigames such as [[Castle Wars]]. The quickest way a player can reset the cooldown is by travelling back and forth through the [[Clan Wars]] [[free-for-all portal|free-for-all (white) portal]], or by drinking from the [[Pool of Refreshment]] (which also removes buffed levels), both located in the [[Ferox Enclave]].

Players cannot bring the imbued heart into legacy duels within the [[Emir's Arena]] to gain an advantage in magical duels if the "no potions" option is enabled.

An imbued heart can be upgraded to a [[saturated heart]] by adding 150,000 [[ancient essence]] to it, increasing the Magic boost by +3, making the boost not gradually drain (like [[divine potion]]s) and reducing the cooldown from 7 minutes to 5 minutes.

==Magic boost by level==

The drop rate of the imbued heart is determined by the [[Slayer]] requirement for the monster being slain. The exact formula is <math>\frac{1}{8 \times \left(200-\left\lfloor\frac{\left(\text{Slayer Req} + 55\right)^2}{125}\right\rfloor\right)} </math>

==Trivia==
*The imbued heart is the ''Old School RuneScape'' equivalent of the {{RSL|Vecna skull}} in ''RuneScape''.
*The animation that appears when using the imbued heart is a blood red version of the [[Saradomin sword]]'s special attack.
*Recoloured versions of the imbued heart were used for the [[Demon's heart (darkness)|Demon's heart]] that were used to imbue the [[god capes]] in the [[Mage Arena II]] miniquest prior to the miniquest's rework.
