Type of Feat: General.
Prerequisite: STR 15, base attack bonus +4 or higher.
Specifics: The character and all nearby allies gain a Damage Shield for 5 turns if they use a polearm. Melee attackers who injure them suffer a die's worth of piercing damage in return. The sides on the damage die increase by 2 for each character with this feat, up to d10 for 5 characters. If only one character has this feat, there is no effect.
Use: Selected. Only one group feat can affect a character at once.
Note[]
If another character uses a polearm and they are within 5 feet of a character with Phalanx Fighting, they benefit from the Damage Shield, but they do not contribute to increasing the damage die of the Damage Shield.
