Retrial Key

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04) without the mods it depends on: it stopped at org.spongepowered.include.com.google.gson.GsonBuilder, a class from another mod or library the stand did not have.

In the author's words

Add an item to force Trial Spawner to skip its cooldown time.
