CAGE
Approach. Aim. Seal. Carry. Awaken.
Why it exists
CAGE is a relic you find, not a tool you craft. Aim at a monster spawner and seal it. The block is gone — no XP, no silk-touch drop. A sealed cage floats where it stood. Plant that seal as a dormant core. Use CAGE on the core and the spawner wakes again, same mob, same timing.
What it does
It is not Silk Touch. It does not clone. One capture is one core, then one spawner. Copies of the sealed item cannot plant a second cage. Trial Spawners use the same Relic and the same sealed item. A sealed Trial looks like a Trial Spawner (ominous if it was ominous), not like the monster-spawner cage. Custom spawner blocks from other mods are out of this release. A vanilla spawner with a modded mob is fine.
Sneak + empty hand on the core picks the seal back up. No cost. Sneak + use in the air opens Infuse. Maximum charge 100.
Lapis +1, amethyst +2, emerald +5, diamond +12, echo shard +20. The offering must fit entirely: if the Relic cannot take the whole offering, nothing is consumed. Creative skips seal and awaken fuel; Infuse still drinks materials.
How it fits
No recipe. Rare loot, about 4% per matching chest: pillager outposts, jungle temples, ruined portals, bastions, and Trial Chamber rewards. Numbers (costs, range, warmup, fuel) live in the server config.
