Attacks

Seren's Special Attacks

Seren uses two styles for her basic attacks: Magic and Ranged. Knowing which protection prayers to use is simple, if you know what to look for. While there is a set pattern which you can memorize, you can also just watch Seren's shadow. It will start each cycle appearing pink, which signals her Magic attacks. Then the shadow turns a deep red, which signals her Ranged attacks.

NOTE: You cannot fully protect against Seren's attacks. Protection prayers decrease her attacks' accuracy, but they can still hit very high.

Deadly Special Attack

"Once I am done with you all, I will destroy all of Xeros!"

This targets all players within the boss room and deals 70-85% of the player's maximum hitpoints. This damage is completely unavoidable.

Healing Special Attack

This special attack's activation has no dialogue signal, but Seren's form will suddenly vanish and quickly be replaced by a large red crystal in the center of the room.

Seren cannot be attacked in this state.

Seren then summons her minions. Whirlwinds around her will immediately start healing her, and crystalline Dark Beasts will spawn in the corners and slowly walk toward her. If they reach her, they will sacrifice their own HP to heal Seren.

It is advised to quickly freeze the Dark Beasts with a binding spell such as Ice Barrage, then destroy the Whirlwinds (they only have 1 HP), then attack the Dark Beasts again, freezing them as necessary.

Weakling Special Attack

"[player], you are the filth within this room!"

"[player], you are pathetic!"

Seren will target the player with the least percentage of their remaining hitpoints. That player will be frozen and 4 smaller Serens will spawn around them, dealing up to a maximum of 85 damage combined. After the attack, the "weakling" will be able to move again.

Spin Special Attack

"Come here you pesky rats!"

This pulls all players within the boss room right next to her. The players have 2 seconds to react to this attack before she spins. The spin will deal 30-60 untyped damage to any player who is still too close to Seren.

After the Kill

Players will be given a stackable blue crystal called "Seren's Key" after each successful kill. This key can be sold to other players or used to open Seren's Chest, located just outside Seren's cave.

Seren will not respawn. If you wish to start another fight immediately, use the Seren teleport or climb the rope in the center of the room, then click on the Rift again to re-enter.


Remember

Encouraging message! Keep practicing and upgrading your gear to defeat Seren efficiently.

Good luck message! May the spells be ever in your favor.
