Keen Hearing and Smell.
The Fernhunter has advantage on Wisdom (Perception) checks that rely on hearing or smell
Pack Tactics
The Fernhunter has advantage on attack rolls against a creature if at least one of the Fernhunter’s allies is within 5ft of the creature and isn’t incapacitated
Bite
Melee Weapon Attack: +5 to hit, reach 5ft., one target
Hit: 8 (2d4+3) piercing damage. If the target is a Medium or smaller creature and the Fernhunter is not already grappling a creature it must succeed on a DC 13 Str saving throw or be grappled and restrained in ensnaring vines that grow from the Fernhunters body.
While the Fernhunter is restraining a creature it cannot move or attack any other targets.
Larger and more aggressive variants of the Fernhound, these plants are vicious pack hunters, restraining prey in their prehensile vines.
