How to learn

Classes:

• Class level 3: Druid, Nature Domain (Domain Spell), and Circle of the Land (Arctic or Mountain)
• Class level 5: Ranger
• Class level 6: College of Lore (via Magical Secrets)
• Class level 10: Bard (via Magical Secrets)

Notes

• This spell requires  Concentration; casting other concentration spell like  Hunter's Mark will remove the surface.
• Damage from this spell is negated by  Land's Stride: Plants. Circle of the Land druids, Wildheart barbarians, and rangers are able to navigate Spike Growth completely unimpeded once they acquire this hidden feature at levels 6 and 8 respectively.
  • Other forms of Difficult Terrain immunity such as  Freedom of Movement, while allowing full movement, do not prevent damage while traversing this spell's area.

Bugs

• The level 4 version of this spell incorrectly uses a level 3 spell slot.
