Faerie Dragons cast their spells at Advanced magic level, with spell power equal to five times the number of dragons in the stack. In theory, this allows them to cast spells with virtually unlimited power.

Faerie Dragon spells are affected by a hero’s Sorcery secondary skill and by elemental orbs — with the exception of Magic Arrow, Ice Bolt, and Lightning Bolt, which remain unaffected.
