How it works

+4 Strength and +4 Constitution, or +6 each from Barbarian level 15. Mighty Rage adds +6 more to both.
You also get a Will save bonus of half that amount, and -2 Armor Class.
If your Strength is already at the bonus limit, the Strength you cannot use becomes attack bonus instead: +1 attack bonus per 2 points.
With Mighty Rage you also deal extra bludgeoning damage equal to the Strength bonus.
A pure Barbarian at maximum level that has taken Mighty Rage and activates Barbarian Rage gets Mind Spells Immunity while the rage is active.
You cannot rage with a natural Constitution modifier below 1.
Only your Barbarian levels count toward the level 15 bonus.
Raging again replaces the rage you already have.

No class learns this from a spellbook. It is used through a feat, and the feat's page describes it too.

Cast by a feat: Barbarian Rage, Greater Rage.
