Base Druid Changes
While in beast form, you gain a +2 power bonus to all defenses.
Sentinel Changes
You gain one druid encounter attack power, up to your character level.
Protector Changes
You can use Summon Natural Ally once per encounter.
Universal Druid Changes
Only characters with the elf or half-elf racial theme can use primal powers. A character cannot multi-class druid if they are not an elf or half-elf.
Charm Beast and Dominate beast are no longer encounter attack power options. Instead, all druids gain the ability to cast Charm Beast once per encounter, or dominate beast once per encounter (starting at 23rd level). However, the powers only work on beasts. If used on a creature with HP equal to or less than the druid's level, the power lasts until the end of the encounter (or indefinitely, at the DM's discretion).
