Necrotic Treestride (move; at-will) ✦ Necrotic, Teleportation

A thicket dryad lich teleports up to 8 squares if it begins and ends the move adjacent to a tree, a treant, or a plant of Large size or bigger. When it teleports in this manner, a thicket dryad lich deals 10 necrotic damage to all nonplant creatures adjacent to it at the end of the teleport.

Thorny Body

A creature that a thicket dryad lich has grabbed takes 10 damage when the dryad sustains the grab.

Indestructible

When a thicket dryad lich is reduced to 0 hit points, it dissipates into a spray of dead leaves, but it is not truly destroyed. It reappears in 1d10 days within 1 square of its phylactery tree, unless the phylactery tree is also found and destroyed.
