How to Complete Key Upgrade Activity
Kill Zombies Within the Scorched Platform
Kill the zombies while you're inside the scorched platform (purple circle) to summon a tanky special zombie.
Killing the special zombie will summon a reward rift that contains either an upgraded version of the purple rarity keys (if you brought them) or a Flawless Aetherium Crystal and Legendary Aether Tool.
Keep in mind that this activity needs to be done in a short amount of time, failing to do so will nullify your progress and you'll have to restart the activity.
