Boar Matriarchs tend to make their appearance during special missions and events. They can also be found as invaders on the Boar Badlands.
The Boar has two attacks. The first of which is a basic Bite/Shove/Tusk attack that hits one target.
The second attack, Trample, has a 1-2 range and will attack the entire row. Despite being Contact, if the Boar can target an exposed unit on the 2nd row, the attack will hit EVERYONE on that row, even if units are hiding behind other units on the first row. Fortunately there is a lengthy cooldown on this attack.
