Type of Feat: General.
Prerequisite: CON 13, base attack bonus +4 or higher.
Specifics: The character and all nearby allies gain Concealment for 5 turns if they wield a shield. The bonus increases by 5% for each character that has this feat up to a maximum of 25%. If only one character has the feat, there is no effect.
Use: Selected. Only one group feat can affect a character at once.
Note[]
If another character uses a shield and they are within 5 feet of a character with Shield Wall, they benefit from concealment, but they do not contribute to increasing concealment.
