Eternal Trial

The Eternal Trial is a challenge room added as apart of the Eternal Palace DLC. It is an endless Eternal Ordeal-styled trial of enemies and bosses found all throughout Hallownest. For anyone who wants to test their strength against the entire kingdom of Hallownest (and Pharloom?), this is the place. It had replaced the scrapped Trial of the Silencer that was originally planned to be apart of the Colosseum of Fools.

The Eternal Trial takes place in the Pale Arena, watched by the Pale King and several members of the Royal Party.

While the Eternal Trial is infinite, there are certain milestones that grant rewards:
 * Defeating 10 enemies rewards a King's Idol
 * Defeating 25 enemies rewards a Mask Shard
 * Defeating 50 enemies rewards the Mosskin Mask charm
 * Defeating 100 enemies rewards an Arcane Egg
