Stage One: The Cinderweb
Beth'tilac retreats to the top of her web at the beginning of the encounter.

Fire Energy
Beth'tilac slowly loses Fire Energy over time. Cinderweb Drones also siphon some of her energy when their own energy is depleted. Whenever Beth'tilac runs out of Fire Energy, she will set herself ablaze, causing Smoldering Devastation.

• Meteor Burn - Meteors crash down onto the web, inflicting 40000 Fire damage to players within 7 yards of the impact. The meteor also burns a hole in the web through which players may fall.
• Consume - Beth'tilac consumes Cinderweb Spiderlings, healing Beth'tilac for 10% of her maximum health.
• Smoldering Devastation - When Beth'tilac's Fire Energy fully depletes, she will set herself ablaze and inflict 400000 Fire damage on all players located at her same level.

Cinderweb Spinner
Cinderweb Spinners dangle from the web above on a filament strand. Using Taunt or a similar ability on a Spinner will cause them to drop to the ground. Once killed, their web filament remains. Players may then interact with the filament and move to the top of the web.

• Burning Acid - The Cinderweb Spinner spits burning venom at a random player, inflicting 20000 Fire damage.
• Fiery Web Spin - The Cinderweb Spinner channels a fiery web onto a random player, stunning them for 25 sec.

These large spiders climb out of caves below the Cinderweb. When their Fire Energy fully depletes, the Cinderweb Drone climbs up to Beth'tilac and siphons Fire Energy from her.

• Consume - Cinderweb Drones consume a Cinderweb Spiderling, healing itself for 20% of its maximum life, increasing damage dealt by 20%, and increasing movement speed by 20%.

• Fixate - The Cinderweb Drone fixates on a random player, ignoring all other targets but decreasing its damage dealt by 75% for 10 sec.

Cinderweb Spiderling
These tiny spiders climb out of caves below the Cinderweb. They instinctively move towards Cinderweb Drones.

Cinderweb Broodling
These unstable spiders fixate on a random player and cast Volatile Burst when they reach their target.

• Volatile Burst - Cinderweb Broodlings explode when they reach a player, inflicting 45000 Fire damage to all enemies within 8 yards.

Stage Two: The Frenzy!
After she has performed Smoldering Devastation three times, Beth'tilac enters a frenzy. She lowers herself from the safety of the top of her Cinderweb and no longer calls for aid from her brood.

• Frenzy - Beth'tilac periodically casts Frenzy, increasing her damage dealt by 5% until the end of the encounter. This effect stacks.
• The Widow's Kiss - Beth'tilac's deadly kiss boils the blood of her current target, reducing the healing dealt to the target by % every 2 seconds for 20 sec. The kiss also causes the target to inflict increasing Fire damage to their surrounding allies within 10 yards.
