Bison

The bison can only be found in the second area and often spawns alone but also sometimes in groups of other bisons or animals.

The bison does not attack the player unless provoked by either getting too close or hurting it. Therefore the bison counts as innocent NPC, not as enemy.

The bison has a lot of health and long-ranged dash attacks that deal significant damage, making fights against bisons very risky and costly.

Behavior
Like all animals the bison roams its spawn area. Because it is not aggressive, but innocent, unless provoked there is no attention indicator visible, even if the bison is aware of the player.

If the bison is attacked or approached to close the bison will turn aggressive and attack the player with dash attacks.

The bison is very fast but large, making it easy to hit. The bison can also be hit while dashing.

Tactics
Upon death the bison will often drop medicine and rarely even a large medicine, making the attack a high risk high reward situation.

It's best attack while the bison is still unaware of the player to get that critical hit.

Weapons that deal a lot of damage on long range are best to be used here. Dodging is key to evade the dash attacks.

Trivia
Like all animals bisons will not drop any ammo or weapon when killed.

The bison rifle will always do critical hits against bisons, dealing 110 damage (55 × ), which is enough to kill some bisons with a single hit.
