Nail beast

Nail beasts are a bunch of ngrngrngrngrngrngrngrngrs. There are 3 levels for the 3 different paths chosen: level 69 on easy, level 98 on medium, level 141 on hard. The number you encounter depends on the level of your follower: 3 for strong, 4 for medium, 5 for weak. (This is the same pattern as for other events.) Therefore you encounter 3 level 69 beasts on the easiest path with the strongest follower, and 5 level 141 beasts on the hardest path with the weakest follower.

They are not very strong, but they hit very fast with melee (it hits 3 times every attack), so keep an eye on your escort's hitpoints. These also damage Barrows Equipment almost two times as fast as regular monsters would.

They move towards you relatively slowly, so you should be able to get in front of your follower and position yourself to shield him/her. They can be poisoned, and they are weak against melee.

You need to kill all of them to complete the event for maximum reward, or most of them before you can evade. (Same as with other events.)
