Savage Defense

Savage Defense is a passive druid ability, added in patch 3.1.0. When a druid in Bear Form deals a non-periodic critical strike, the druid has a 50% chance to gain a damage shield equal to 35% of their attack power. The next hit completely removes the shield regardless of how much damage was done.

It is learned at level 40 for.

Note
This ability (together with the Natural Reaction talent) could be an attempt to make up for the lack of block (and parry) abilities of feral druids. Savage Defense as well as block value are both increased by an otherwise offensive stat — attack power and strength — so they scale based on the same principles. This change reflects Blizzard's plan to remove the differences between tanking classes.
