Dragon Kill Points

Criteria:
Defeat Melidrussa after defeating 40 of her chamber's Infused Whelps in Ruby Life Pools on Mythic difficulty.

Strategy:
As simple as it sounds, you can choose to spawn whelps on your own, which is highly recommended. Each egg pool has ten eggs, so manually spawn four groups, eliminate the whelps, and you're done! Defeat the boss as normal.

Easy Solo for Level 80-100 Worldsoul Saga & Beyond...

0. Achievement Tracker enabled will turn from Red to White once 40 Infused Whelps have been defeated.

1. Mythic Difficulty

2. I was able to stealth my way past all the trash to the boss, much quicker.

3. Anyways, enter boss room and pull boss.

4. Notice the Infused Dragon eggs on the side pools. Run in there and step all over the eggs. Kill the whelps. Rinse & repeat. I usually just stuck to the right side of the room.

5. All in the meantime, reduce boss health but do not kill her until you have 40 Infused Whelps defeated.

6. Finally, with achievement criteria met, nuke boss down.

7. ?

8. Profit. Achievement Completed.

Protip: Just run over the eggs in the boss room.

Adds spawn. Kill adds. Profit.
