Legion Fiend

''These demons are disciplined enough to follow orders and to fight in formation, unlike most of their kind. Their unity of will is attributed to the blackened armour they wear to contain their chaotic energy.''

Legion Health - Legion fiends seem to absorb blow after blow, fighting on despite massive injuries, until a single decisive attack against one causes all of them to fall to the ground, slain. Adjacent legion fiends combine their hit points into one large pool. If the pool is reduced to 0, all the legion fiends in it immediately die.

Legion Saves - If a spell or other effect that allows a saving throw targets more than one legion  fiend, all the  fiend s use the highest d20 result rolled by the group. If a mind-affecting spell or ability targets a single legion  fiend, all other adjacent  fiend s saving throws against it. If any  fiend  succeeds, all the  fiend s succeed. If all the  fiend s fail, they all suffer the effect of a failed save.

Legion Attack - Trained and experienced in working together, legion  fiend s gain a +4 bonus on attack rolls for every other adjacent legion  fiend.
