Khaar

Khaar is the first boss added in the Zenek's Additions mod. It has the usual worm AI, but is able to shoot a slowing white projectile.

It attacks by burrowing underground for some time and then jumping out at the player unexpectedly, also using it's slowing white web to ensure his next attack will hit. The battle can be long and tiresome, so make sure to go bring some effective weapons against worms/armor.

Remember that Khaar's defence varies between body parts, the tail has 30, the body 20, and the head has a lowly number of 10. While this probably won't change much in your strategy, you should aim for the head with your powerful non-piercing attacks and avoid the tail.

It drops the Khaar's fang, Antago Sword, Antago Staff and Antago Crossbow. They all drop at a 25% chance, however due to how it's coded, multiple items can drop at once or none at all.

It can be summoned anywhere using the Demonic Bone.

In the progression, Khaar can be fought right after skeletron but it is advised to kill him with the best pre-WoF gear.

Has it's own theme that plays when you fight him.
