Bear Totem Barbarian

At 1st level, a bear totem barbarian gains Improved Grapple as a bonus feat, even if he doesn’t meet the normal prerequisites.

At 2nd level, a bear totem barbarian is able to start a grapple as a free action after making a successful melee attack. The attack deals damage normally. Improved grab can only be used on creatures the same size or smaller than the barbarian.

The barbarian must have at least one hand free in order to initiate a grapple using this ability.

At 3rd-level, a barbarian gains 2 extra hit points per barbarian class level. This ability counts as the Toughness feat for the purposes of meeting prerequisites.

Starting at 5th level, a bear totem barbarian counts as one size category larger for all grapple checks, if it’s advantageous to him to do so. Among the other benefits, this allows the barbarian to grapple larger creatures and use his improved grab ability against creatures up to one size category larger than his own. The amount of damage dealt by his unarmed strike when using the Damage Your Opponent grapple action is also increased by this effect.

At 9th level, a bear totem barbarian is instead treated as being two size categories larger while grappling and can use one-handed weapons to attack while grappling in addition to light weapons.
