General Rewards

How to Beat Lassal The Flame Spun

Avoid Spending Resources in Phase 1

Quickly Eliminate Summoned Slagspitters

Always Mind Your Position

Avoid Resurrecting Allies in Phase 4

Avoid Spending Resources in Phase 1

Phase 1 is the easiest part of the fight. Focus on attacking and dodging Lassal's jump attack if it uses it. This phase should be a breeze if your character has the necessary stat for the raid.

Quickly Eliminate Summoned Slagspitters

When Lassal summons the Slagspitters anytime during the fight, make sure to prioritize killing them asap. They can deal continuous damage to your party and if Lassal's attack connects while your HP is low, you may potentially die and have the raid fail.

Always Mind Your Position

Positioning is the most critical aspect of the Lassal Raid, especially during its boulder attack. Know your class and always position yourself in the most ideal area for your attack range. Stay far if you're a ranged class and position near and away from molten cracks if you're a melee class.

Avoid Resurrecting Allies in Phase 4

Phase 4 causes Lassal to go wild and start using its attack at a rapid pace. Your revive will be interrupted easily so it's better to dish out damage during this phase and end the fight immediately. You can revive your fallen allies after the battle concludes.

Don't Waste Your Own Revive

During the raid, you can spend one free revive without the assistance of an ally and at full HP as well. Make sure to use this sparingly and as much as possible, only use this during phase 3 or 4. Have your ally revive you during the easier phases.

Lassal The Flame Spun Attack Patterns

Phase 1 Attack Patterns

Phase 2 Attack Patterns

Phase 3 Attack Patterns

Phase 4 Attack Patterns

Phase 1 Attack Patterns

Jump Slams

This is Lassal's strongest attack for Phase 1. He can hop around the map and land in a large area that targets one player. This repeats multiple times and you cannot run towards him as Lassal's hitbox will block your movement.

Phase 2 Attack Patterns

Flame Arc

This is a large attack but it has a long charge time. It is easier to move behind Lassal when he charges for this move if you're melee and away if you're ranged (and in the right position).

Summon Demons and Slagspitters

Lassal summons several demons and Slagspitters who will relentlessly attack the players during the raid. The Slagspitters in particular can deal huge amounts of damage to the players.

Flame Arc Ignite

Lassal ignites the molten cracks created by its Flame Arc attack. Make sure to position yourself away during these molten cracks at all times!

Phase 3 Attack Patterns

AoE Boulder Attack

Lassal summons a boulder on the battlefield. After a short while, any player that is not positioned behind the boulder will take massive damage and likely die if their defensive stats and Combat Rating are near the suggested Combat Rating requirement.

Phase 4 Attack Patterns

All Movesets

When Lassal enters Phase 4 which is its last bits of HP. He goes into a frenzy and he gains an increased attack rate. In addition to this, all moves he uses during phases 1 to 3 will be usable in this phase. It's highly recommended to use all your ultimates during this phase if available.
