Adria is Diablo's servant, who is obsessed with freeing him from the stone of souls. Before the battle begins, Adria will show you her true form - a winged, spider-legged demon.
Single blows should do no damage to her but, she cannot be taken lightly. You need to attach the most attention to the larvae of her blood, which abound towards the end of the battle. Even if you take damage from one, you quickly need to leave the field of the puddle that appears there. During the encounter, you should move around the arena carefully, as her larvae will get under your feet constantly. Adria summons the larvae many times and apart from that, she also use the whirlwind and the ball of blood, attacks that need to be avoided like the plague.
Wing Slash - Adria performs a wing swing and deals damage to the characters in front of her. It is recommended that you hop back from that.
Whirlwind - Adria starts spinning, drills into the ground and appears next to the character of her choice. Deals medium damage.
Blood Ball- Adria charges the attack and places a ring of violet flames under your feet. The effect of this skill is the same as that of the Defiler, which some of the elite mobs have at their disposal.
Blood splash - Adria starts using this skill as soon as her health bar drops to a predetermined level. The larvae of blood appear then, and they start crawling into random directions. They do not attempt to approach any of the characters with premeditation so, you can avoid stepping on them. Whenever they touch to you, they explode, which deals low damage but, under your feet, there appears a pool of blood, which deals high damage, if you stand on it for too long.

Even if they use them and you do not, you will get the achievement anyways.
