Fire Flak

Phase 1=|-|Phase 2=|-|Phase 3=|-|Phase 4= The Fire Flak is a level 20 miniboss found atop Vagrant Van's Tower in the northwestern Detlas Suburbs.

Combat
The Fire Flak has a total of four phases. All four forms deal damage, have defense against  attacks, and are weak to  damage. However, in its first phase, it has only 10 health and does not actually attack at all, despite appearing hostile. The second phase spawns and the fight truly begins once the first is killed.

Each of the three successive forms possesses 90 health per mob, and each is a ranged enemy that attacks at a difference, though their exact styles vary. The second phase attacks by shooting large bursts of projectiles all at once, with long pauses between attacks. This can be dangerous at close range and difficult to avoid, but the pillar in the center of the arena can offer some cover.

After killing the second form, it splits into two third-form Fire Flaks. In this phase, they use regular ranged attacks, simply shooting one projectile at a time (although you should still be careful, now that you are being attacked by two enemies at once). Upon being killed, each of the third-form Fire Flaks splits into two more, in their fourth and final phase. In the fourth phase they shoot projectiles significantly faster, and once again will pause for a short time between each rapid-fire burst.

The 8 individual Fire Flaks spawned during this fight possess a collective total of 640 health. There are no other minions involved in this fight, but the splitting mechanic and the boss' wide range of attack styles can make it extremely chaotic. The Fire Flaks can also damage each other, however, so keeping them close together and in each other's way can make them easier to take on.

Loot
By climbing the ladder in the center of the arena, either before or after defeating the Fire Flak, you can access a Tier IV Loot Chest, and leave the tower by jumping down into a pool of water on the ground below. Since the first form of the Fire Flak doesn't attack, you can actually bypass the fight entirely if you simply want to reach the Loot Chest.

The Fire Flak has no special drops of its own, though each individual form can drop Normal Items, Unidentified Items, Emeralds, Powders, and Potions of Healing.

Location
The Fire Flak is located at the very top of the corrupted tower in Detlas Suburbs; Vagrant Van, found on the road between Detlas and Nivla Woods, directs new players towards the tower. To reach the top, you must ascend through several floors containing parkour, Zombies, Smolders and Slag Coats.
