Extinction's Heaven

Introduction

• This is one of 5 dungeons in the Mountain of Exiles dungeon series.
• The boss is Devastar the Pure Blooded
• 6.88 Tillions HP
• Type: Demon, Human

Phase 1 Devastar

• He has multiple patterns that shoot lasers all over the place. Try your best to avoid them. Examples below:

Chaos Barrier Pattern

• He summons a large circle in the room with pillars around it.
• You will see 4 pillars light up. Your job is to stand on the lighted pillars. Failing will cause KO.
• Successfully do this 3 times will generate groggy.

• NOTE: If you miss and didn't see which one lighted up, you can walk around the pillars to see which one light up. 

Phase 2 Devastar

• He will enter phase 2 if HP drops below 70%.
• Just like other bosses, he has patterns that can be dodge by avoiding the lighted up area on the ground. Examples below:

Execution Pattern

• He summons orbs in the sky that shoot dark swords around the room.
• The swords then explode. These explosions are big and pretty much cover the whole room.
• Stand inside the yellow pillar for safety. 

• NOTE: Getting hit by the swords as they're dropping down doesn't hurt but it will knock you down, making it difficult to run to the safe spot. Use Super Armor Potion  here.

Energy Emission Pattern

• He summons 4 portals on the 3,6,9,12 o'clock then he starts releasing dark energy dealing damage.
• Step on 1 of those 4 portals to levitate into the air, avoiding the dark energy.

Apocalypse Pattern

• He summons 6 crystals that rotate clockwise.
• He also summons 2 aircrafts that follow players and shoot lasers to the ground. The lasers will bound back as they hit the ground.
• Your job is to guide the aircrafts so that they shoot the lasers on the ground, bound back and break the flying crystals.
• Breaking all 6 crystals before the progress bar fill up will generate groggy.

• Failing the pattern will pretty much create KO hit.
• He jumps and sucks everyone in, brings your HP to 0 but won't kill you, then slams down with a final AoE.

• TIP: Since there are 2 aircrafts and 4 party members, it's hard to know which person the aircrafts follow. Since the aircrafts fire laser quite frequently, everyone should stay together in one spot, so both aircrafts can concentrate their shots. Due to the high shooting frequency, these shots will pretty much guarantee to hit the crystals when they pass by.

Strategy

• Groggy duration for phase 1 is short, and it can be hard to find the lighted up pillars, most party would force phase 2 to open by doing the most DPS to get HP below 70%.
• For phase 2 apocalypse pattern, everyone stay in one spot to destroy the patterns. If you happen to fail the pattern, your HP is down to 0 but you won't die, use your potion and run to the edge of the room before he slam down to avoid dying.
• Beside that, the rest of his pattern can be easily avoided.
