|This heart holds a magical power within.|
The imbued heart is a magic-boosting item dropped by superior slayer monsters, which are rare encounters unlocked after purchasing the unlock Bigger and Badder for 150 Slayer reward points from any Slayer master.
The rarity of the imbued heart dropping correlates to the Slayer level requirement for the monster. For example, the effective rate to obtain the heart from Insatiable Bloodvelds is 1 in 894.4, while for Nuclear smoke devils it is 1 in 197.6.
Players can use the Invigorate option on the heart to temporarily raise their Magic level by 2-10 (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 boost will not work while your magic level is already boosted by any other effect. Players additionally cannot bring the imbued heart into the Duel Arena to gain an advantage in magical duels if the "no potions" option is enabled.
