Familiar: You gain a dwarf caiman familiar. Your effective wizard level for this ability is equal to your druid level. Your druid level stacks with levels from other classes that grant familiars when determining the powers of your familiar.

Death Roll (Ex): While grappling an enemy up to one size category larger than you, you may make a grapple check to roll wildly, knocking your enemy prone and dealing 1d8 points of damage. When using this ability, you gain a bonus to your CMB equal to one half your druid level (minimum 1). You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

Ambush (Ex) : At 6th level, you gain sneak attack +1d6. This increase to sneak attack damage stacks with sneak attack damage you may have from other sources. This sneak attack damage increases by +1d6 for every 5 druid levels you possess beyond 6th, to a maximum of +3d6 at 16th level.
