Feat: Defensive Growth
Trigger You're the target of a physical attack.
You grow a shield of woven flowers and branches, then Raise that Shield to defend yourself from the triggering attack. If you would take damage from the attack, you immediately Shield Block. This is a Wooden Shield (Hardness 3, HP 12, BT 6). The shield remains in your possession for a number of rounds equal to your level, or until it's destroyed.
Awakening The shield becomes stronger. It has Hardness 5, HP 40, BT 20.
Awakening The shield takes on a mind of its own and lashes out vengefully when destroyed. When the shield is destroyed, is explodes, dealing 4d6 piercing damage to your attacker, with a Basic Reflex save.
