Ivern cannot attack or damage non-epic monsters. Instead, targeting a jungle camp initiates a 2.5-second channel that, upon completion, places the monsters within a grove. Placing a grove costs health and mana, and cannot be cast if Ivern lacks the resources.
The grove matures over 40 - 6 (based on level) seconds. When fully matured, Ivern can interact with the camp again to instantly free the monsters, sending them away while receiving their full gold and experiencebounty. Smiting a camp within a grove will instantly free the monsters, regardless of its maturity or the monster's current health.
If the camp's large monster has already been slain, Ivern will free the camp upon completing the channel at no cost. Similarly, the grove will instantly mature if the large monster is slain.
Starting at level 5, freeing the Red Brambleback or Blue Sentinel leaves behind a sapling that can be picked up by an allied champion to gain the camp's buff, consuming it in the process. If at least one allied champion is nearby, Ivern can pick up the sapling to transfer it to the nearest one in range. If an ally kills either monster, they also leave behind a sapling that only Ivern can consume.
