Fall of the Outcasts Abomination Guide

The Abomination is the final boss of the Fall of the Outcasts Monolith Timeline in Last Epoch. It is also the very first Harbinger you will have to fight. However, he is easier to beat than some of the campaign bosses (such as Lagon for example), but this does not mean you can come unprepared. He can have some punishing mechanics.

Here is a breakdown of all major abilities used by the Abomination.

Phase 1 starts with an Invulnerable boss, and four Vessels you need to destroy to activate the boss. The four vessels are located in each map corners. Be careful, as the Vessels will attack with necrotic AoE damage around them while you try to destroy them. Once each vessel is destroyed, Necrotic pools will cover the quadrant of the arena in which it was in. Once all four Soul Vessels have been destroyed, it will leave only a circle in the middle as safe. This is the only spot you can fight the Abomination in.

The Abomination will launch three simultaneous circle AoE attacks; one around his tail, and two linear shots (one in front of him directed at the closest player, and one behind him). These ignite on hit and deal massive Fire damage. When he starts lifting his tail you will want to move away.

The Abomination will launch three necrotic waves in front of him. The wave will return to him after a while. Be careful as you can get hit when they launch and when they come back. These deal necrotic damage and apply Damned.

The Abomination launches a sort of Earthquake in a straight line towards a player, which will erupt at the exact spot you were standing. Using Evade here is a good way to ensure you're never hit by this.

The Abomination spawns four Necrotic AoE zones that will chase you and deal necrotic DoT. The longer they are on the arena, the more damage over time they will deal. These can sometimes also be spawned at the same time as Earthquakes.

He will do a big slash in front of him. This deals rather low necrotic damage and can be tanked by almost any build.

The Abomination is invulnerable at the start. Your goal is to destroy four Soul Vessels placed in the corners of the lower arena.

• As you try to destroy them, they will constantly attack you.
• Each Vessel periodically fires a Necrotic AoE when you are nearby.
• When a Vessel is destroyed, it leaves behind a large Necrotic Pool in that area — avoid stepping into these zones afterward.

Destroy all four vessels while staying ahead of the boss. Try moving in a clockwise or counter-clockwise pattern to keep the arena manageable. Once the last vessel is destroyed, Phase 2 begins.

The final stage takes place on the center platform. The outer arena is now covered in Necrotic Pools, so stepping outside is lethal.

• Recognize and avoid predictable attacks like Tail Flare and Necrotic Wave.
• Use the space efficiently, and time your movement cooldowns.
• Damage windows are frequent, but do not get greedy — play safe and consistent.

• 75% Necrotic Resistance
• 75% Fire Resistance
• Movement skill on cooldown helps greatly

The Abomination has four possible unique drops, all listed below

Woven Flesh and Ribbons of Blood are both common drops with a 50% chance of dropping. They are mutually exclusive, meaning you will only receive one of them, not both. These drops can occur in both Normal and Empowered versions, and their drop rates are not affected by Corruption.

Flayer's Pride is not commonly obtained and is considered a rare drop. The likelihood of obtaining this item is affected by higher levels of Corruption. Although it is possible for it to drop from a non-Empowered Abomination, farming on Empowered difficulty is strongly recommended.

Strands of Souls is another rare drop, but it only drops in Empowered difficulty. The drop rate of this item improves with higher levels of Corruption.

The Harbinger for this Timeline if the Harbinger of Defilement. He will keep some skills from The Abomination:

• He will create multiple Necrotic pools on the ground. Avoid stepping into those.
• He will slam into the ground, dealing a large AoE Fire attack. You can easily avoid it since you see the fire circle on the ground before it hits, giving you time to move out.

• Aberroth's Command
• Harbinger's Needle

Additionally, Harbingers drop the Harbinger Eye which is needed if you want to summon Aberroth.
