The Planula is a boss item in Risk of Rain 2, dropped by the Grandparent.png Grandparent.

Whenever the holder takes damage, they immediately heal 15 HP (+15 HP per stack), making it extremely useful against monsters that attack with rapid, low-damage hits.


  • Damage-over-time debuffs, fall damage, and damage from the Void Fields trigger the heal.


  • Since the Planula's healing is applied after taking damage, it will not prevent the holder from dying even if the resultant healing would bring them back above 0 health.
  • The Planula works well with the Helfire Tincture.png Helfire TinctureBgLunar.pngHelfire Tincture.png45sBurn everything nearby... including you and allies.

  • REX.png REX makes excellent use of the Planula, since it heals them when they pay HP for abilities.

  • Inside the egg, a tinyParent.png Parent can be seen.
  • While written to sound humorously confusing, this item's logbook entry suggests that the Parent species has a similar life cycle to that of stars; they start out normal-sized, expand into giants over time, and then collapse into smaller versions, which are the oldest. This may also explain why the species glows brightly, and why Grandparents have a "sunlight" attack.
    • Since this logbook entry reveals that Children from Risk of Rain 1 are actually the eldest of the Parent species, their disappearance from Risk of Rain 2 may potentially be a result of the Survivor from the first game killing them. If this is the case, it can be surmised that not enough time has passed for the Grandparents to mature into Children, but enough time has passed for the previous generations of Parents to grow into Grandparents.
