Slammer

Slammers are big blue birds with five eyes and pink darts embedded in their back. They are found in the Corrupted Prison, Cavern and Astrolab.

Slammers lack feathers on their body and wings, probably explaining why they cannot fly. The tranquilizer darts and collar with a broken chain hint they may have been beasts of burden before the Malaise outbreak.

Behavior
When a Slammer detects the player, it will jump at the player to get within range. It can jump between platforms to chase the player. If the player is on the same platform as them, it will do a faster leap forward.

Slammers are immune to stun.

Slammer Elites, on top of any Elite special abilities, are faster than normal.

Strategy
Slammers are one of the hardest enemies in the game. They are extremely aggressive, have high HP, attack incredibly fast, and their attack covers a large amount of ground. Even if you roll behind them to dodge their attack, it can very quickly turn around and do it again.

Their only real weakness is that they are vulnerable while they are jumping between platforms. You can exploit this to get one free hit on them right when they land. Rooting them while their back is turned against you is the most effective way to kill a Slammer, which it can't do anything about. Burst damage and freeze skills are very useful to have in case you can't kill a Slammer fast enough.

Alternatively if there are climbable chains nearby you can take advantage of them and use deployed skills without worrying about the Slammer's attack.

If you do let a Slammer start attacking, stay on the air for as much as possible, especially while they are facing you. Get behind them as fast as possible and run to a different platform.

Slammers should be fought 1v1 whenever possible. If there are too many enemies around it, use the Homunculus Rune to draw aggro. Do not dive attack into it because they will not be stunned by it.
