Shrine

Spends gold every year to level up one random plot. The gold cost falls with each Shrine level (9, 6 and 3 gold on the official wiki table).

How players use it

King of Time Portal loops: a Portal sends the kingdom 2 years back at max level. Vao levels it instantly with Shrine and Overwork, loops back to the first council and takes Kintsugi repeatedly. Vao stops after 20 to 25 jumps to avoid breaking the time continuum, which warps the run to year 33 (Patch #27).
Rainbow cards by job Levels: Patronage (+3 base levels beyond the cap), X-Ray (levels every plot diagonal to the target, beyond max level), Shrine (spends gold for a random level-up each year), Mantra (1.0, bearer gains +3% all stats per stack whenever any plot levels up).
Long runs Time Bender (reach a negative year, 4.0%): play the King of Time and chain Portals (each sends you 2 years back; Wormhole adds more) in the early years. Shrines speed up Portal levels. King of Time.

Loot after beating the Jack of Rainbows (twice per run).
Merchants have a chance to stock one; the Lucky perk and Rare Goods decree raise it.
Gacha at max level, Diffract and the Refraction decree give random Rainbow cards.
