 is a challenge in Risk of Rain 2. It is completed as REX by healing 1000 Health in a single tick.

Tips

 * The easiest way to achieve this is to combine a with, which will heal 100% of your max health in a single tick. Then you only need 1000 max health to complete this challenge.
 * A similar strategy would be to combine the with the Rejuvenation Rack, and having at least 1000 max health.
 * Getting a few can help to reach this max health value faster.
 * For Tangling Growth to heal 1000 health in a single tick, you will most likely need two Rejuvenation Racks combined with a large crowd of enemies.
 * Bramble Volley is not recommended. Even with a large group of enemies, the healing from each enemy will be treated as a separate tick.
 * You do not need to be at low health - getting the 1000 healing at full health will complete the challenge.
