Undead Fortitude. If damage reduces the zombie Hill giant to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.
Multiattack. The giant makes two greatclub attacks.
Greatclub. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 18 (3d8 + 5) bludgeoning damage.
Rock. Ranged Weapon Attack: +8 to hit, range 60/240 ft., one target. Hit: 21 (3d10 + 5) bludgeoning damage.
Description
Hill giants are selfish, dimwitted brutes that hunt and raid in constant search of food. Their skins are tan from lives spent beneath the sun, and their weapons are uprooted trees and rocks pulled from the earth.
Some are raised by strong necrotic magic to serve as siege engines for powerful necromancers
With a +5 Con, the Hit dice should be 10d12+50
@lumenbeing I apologize for that friend, feel free to update it at your need :)
You need to add "Darkvision, 60'" under "Senses" as all other zombies have that.
