In Dungeons and Dragons 3.X, (and possibly Pathfinder), is there any way to 'improve' your Rage bonuses?
I know that specifically for 3.X there are a number of different forms of Rage, including:
Ferocity: +4/6/8 Str, +4/6/8 Dex, 4/5/6+Con round duration, −2 ranged attack rolls beyond 30 ft. Resiliant Rage: +4/6/8 Dex, +4/6/8 Con, DR (1/2/3)/–
Whirling Frenzy: +4/6/8 Str, +2/3/4 AC and Reflex, have the option of an extra attack at full BAB in exchange for −2 attack penalty for the roundd
Mountain Rage: Another +2 Str on top of regular bonuses
Aside from Mountain Rage, which is the only thing I know of that actually increases your Rage 'scores,' are there any other ways to improve them besides getting the Greater and Mighty Rages later?
