The term Zombie in Sinkholes is used as a collective term describing two types of zombies using 2 different attack styles. It consists of a warrior and ranger, they can be found on abandoned 1 and 2, occult and warped floors. They have high consititution while having a rather poor defence.
Possibly the most commonly seen variant, they wield two hatchets and they attack by throwing axes at players. They're rather inaccurate but powerful. Upon defeat, they will occasionally drop hatchets of varying tiers depending on what level the zombie was. They are weak to slashing weapons so a battleaxe or two-handed sword will make short work of them.
Similar to the ranger variants they have high constitution but very poor defence, and their attacks are somewhat accurate. They can be seen using hatchets, and can drop them on rare occasions. They can be summoned by Necromancers on the Occult floors. Summoned zombies die after a short period of time, and will only drop bones. These zombies are weak to fire spells.
