Level 90
Slayer and have started
Mourning's Ends Part II is required to kill the Dark Beast (except in Kuradel's Dungeon). No slayer equipment is necessary. Dark Beasts have both Melee and Mage attacks. However, they will only use their Mage attacks if you attack them first, this is a one off attack providing you are within melee distance for its next attack, if you are not it will continue to use magical attacks. While the magic is weak in terms of its max hit, it is accurate. These creatures will always remain aggressive as well.

Tactics
These are difficult to get to. Effective is to use a prayer boosting gear and use protect from melee. Dark beasts have very high range defence. It is more than common to melee them with prayer armour on. Ranging them is only recommended at very high Ranged. (90+)
