How to defeat Artifact reliquary???

[nai249]

After the first key I cant find any others and after a few min I just eventually die. Is there a trick to this fight?

fight the enemies and they will drop more. can only hold one at a time

You can hold more than one, but it uses all of them and only does the damage of one so no point.
Excess keys strewn about the map vanish when you use them too.

Use 'em asap!
If the enemy is floating over the edge the key will drop into the abyss too, so watch out for that.
