Range 120 feet; Area all squares in a 20-foot burst
Duration 1 minute
Plants and fungi burst out or quickly grow, entangling creatures. All surfaces in the area are difficult terrain. Each round that a creature starts its turn in the area, it must attempt a Reflex save. On a failure, it takes a –10-foot circumstance penalty to its Speeds until it leaves the area, and on a critical failure, it's also immobilized for 1 round. Creatures can attempt to Escape to remove these effects.

Concentrate Manipulate Plant Wood Source Rage of Elements pg. 196
Area 30-foot line
Defense basic Reflex
Thorny roots erupt from your hands in a tangled cascade, puncturing creatures in the way of their growth and revitalizing you. You deal 8d6 piercing damage to creatures in the line (basic Reflex save). You gain 1d4 temporary Hit Points for every living creature in the line, as the roots transfer nutrients from those damaged into you. The temporary Hit Points last for 1 minute.
Heightened (+1) The damage increases by 2d6.
Oaken Resilience [two-actions] Spell 2
Concentrate Manipulate Plant Wood Source Player Core pg. 347
Range touch; Targets 1 willing creature
Duration 10 minutes
The target's skin becomes tough, with a consistency like bark or wood. The target gains resistance 2 to bludgeoning and piercing damage and weakness 3 to fire. After the target takes fire damage, it can Dismiss the spell as a free action triggered by taking the damage; doing so doesn't reduce the fire damage the target was dealt.
Heightened (+2) The resistances increase by 2, and the weakness increases by 3.
