Kystia fights alongside her fel-infused mana wyrm Nibbles, and while Nibbles stays infused Kystia sits behind an 80 percent damage-reduction Felshield, so the real opener is burning Nibbles to 20 percent health. Keys die here when groups waste cooldowns into the shielded boss, miss Corroding Spittle dispels, or eat the party-wide pulses of the Destabilized burst window with no healing cooldown ready.
Kick list: Mirror Images
Kystia infuses Nibbles with fel magic, turning the wyrm hostile while it is above 20 percent health; while the infusion holds, Kystia's Felshield reduces the damage she takes by 80 percent.
Treat Nibbles as the kill target from the pull. When Nibbles reaches 20 percent, the wyrm turns friendly and stuns Kystia into her burn phase.
Nibbles spits at players, dealing an immediate Fire hit and a heavy Fire damage-over-time effect that ticks every 3 seconds for 30 seconds.
Healer dispels this Magic debuff the moment it lands; letting it run its full 30 seconds drains the healer for the burst window.
Nibbles unleashes a cone of fel fire in front of her that ticks on anyone caught inside it for 5 seconds.
Melee sidestep out of the cone immediately; the tank should face Nibbles away from the group.
Kystia blasts her current target with heavy Chaos damage that then jumps to nearby players at reduced effectiveness.
Tank uses active mitigation, and everyone else keeps a small gap from the tank so the barrage cannot chain.
Kystia creates copies of herself, and each image casts Felstorm, which engulfs the arena in fel fire ticking on the whole party every second.
Interrupt, stun, or knock every image the moment it spawns; one completed Felstorm is a wipe-level healing check.
Kystia teleports to a random player's location and detonates an explosive wave that damages and knocks back everyone nearby.
When the boss blinks onto a player, everyone runs out of the blast radius before the wave fires.
Once Nibbles is freed, the Light Infusion stuns Kystia for 20 seconds, increases the damage she takes by 115 percent, and pulses Chaos damage into the whole party every second.
Send lust, offensive cooldowns, and a healing cooldown together; this window is where the boss actually dies.
Stack Kystia and Nibbles on top of each other so the group cleaves both, face Fel Spray away, and mitigate every Chaos Barrage.
Dispel Corroding Spittle on sight and bank a major cooldown for the Destabilized pulses, which tick the whole party every second for 20 seconds.
Burst Nibbles down to 20 percent, contribute a stop to every Mirror Image, and dump all cooldowns into the Destabilized window.
Dodge the Fel Spray cone and sprint out when Kystia teleports to a player for Fel Nova.
Tyrannical: The Destabilized pulses and Chaos Barrage chains hit hard enough that each burn window needs a planned healing cooldown, and a completed Felstorm is fatal, so treat every Mirror Image stop as mandatory.
