This is because they become permanently aggressive to the player no matter how long they stay near. Additionally, they have a chance to drop the Dark bow.

Dark Beasts’s Attacks

• Magic attack: Dark beasts will only use magic as their first attack if they are attacked by the player first or if the player is not in melee range. Its magic attack has a max hit of 8.
• Melee attack: Dark Beasts will use their melee attack when the player enters their melee range. It has a max hit of 17, but cannot hit through protect from melee.

Strategy for Killing Dark Beasts

The best strategy to kill Dark Beasts is to pray protect from melee and attack them with melee while wearing your gear with the highest DPS. This way,  they will use their melee attack instead of magic since you are close to them, and you won’t take much damage. You could use a cannon, but it's not worth it, since it will aggro them from a distance and make them use magic more often.
