Dungeon Mechanics

Similar to the last dungeon, the Underground Lava Lake harkens back to base game combat, it is a relatively simple dungeon that can is designed to be completed in the early game of the expansion. This means the dungeon does not require advanced tactics, high levels, or complete optimization. Each monster is pulled directly from the associated Slayer Area, and as the player has been forced to fight each of these monsters before, they should be well versed in their dangers.

Intimidation

Just like every other monster in the , each enemy in the Underground Lava Lake has a passive effect that reduces the player's Damage Reduction. When in combat with Trogark, the player's base damage reduction is reduced by 20%, before any modifiers from the Combat Triangle.

Manual Clear

Manually clearing the Underground Lava Lake is a good way to get to the next dungeon, Lightning Region, as soon as possible.

Changing equipment sets to be able to fight each monster with Combat Triangle advantage can lower the required levels, especially Hitpoints required to clear the dungeon efficiently. The player should already have setups available from clearing each monster in the Lava Lake, but they will look similar to the following Magic build.

Rewards

Completing this dungeon unlocks the Lightning Region dungeon.

Standard Guide

This guide was written up to make the dungeon easily clearable fresh into Throne of the Herald Expansion. It is idleable with the stats and gear provided.
You'll need at least 1,110 HP and 67% Damage Reduction to safely idle this dungeon.

Used for this guide:
Level 100

Point of Interest: The Academia Arcanum

Summoning

Yak and Dragon - Avoids damage from burns inflicted by enemies, particularly useful for Trogark as it nullifies their burn lifesteal passive effect and reduces the maximum damage possible from the Unleashed Power special attack.

Spells

There are three Archaic Spells unlocked by completing Ancient Sanctuary. With Level 100 we can only use Poison Pods for now. This will require you to have Level 112 though. If this has not yet been obtained, just use Fire Surge for now.

Poison Pods or Fire Surge

Using curses and auroras, unsurprisingly, increases your damage done:

Ancient Relics Guide

Tested with Relics:

- 1,2,3,4,5,Master
- 1,2,3,4,5,Master
- 1,2,3,4,5,Master
- 1,2,3,4,5,Master
- 3
- 1,2,3,4,5,Master

With listed Relics there is no death chance using the Standard Guide setup with Level 99, Level 99, Level 99. Fully idle-able.

You can also use Cloudburst Staff instead of Ocean Song/ Shield of Magic Power combo. This results in 0.05 deaths per hour, which is completely negligible.
