"A raised conveyor which passes under the light of a powerful ancient shrine. Doesn't count as an upgrade. 2017 March Exotic."
The Clover Shrine is an Exotic-tier upgrader released in the 2017 St. Patrick's Day Event. It upgrades ores by multiplying their value by 3x. It also does not count as an upgrade, thus allowing ore to be used with cell furnaces after being used with the Clover Shrine.
