Relic Knowledge

In Bloons TD 6, Relic Knowledge is a system consisting of Relics, features which when enabled grant certain enhancements to the player. These enhancements include making certain towers cheaper, increasing the amount of cash or lives, increasing towers' strength in certain situations, and allowing use of a limited number of free Powers in a game. Relics are only accessible when playing in Team Events, which are Contested Territory and Boss Rush.

Contested Territory

See also: Relic Tile

In Contested Territory some tiles are Relic tiles which when captured, allows all players on the capturing team to use its Relic as long as they remain in control of that tile. Each player may only use up to four Relics from captured Relic tiles at a time.

In addition to Relic tiles, there are up to three Event Relics and one Daily Power Relic available for purchase with Team Trophies. Daily Power Relics are a Relic which grants free use of a Power. The Daily Power Relic changes every day, and upon refresh teams must spend Team Trophies again to unlock the new one. Event Relics start out inaccessible, but over the course of an event teams get the opportunity to purchase them. After a team purchases a Daily Power or an Event Relic, players on that team all gain access to that Relic for all tiles. At any given time, all teams have access to the same Event Relics and Daily Power Relics.

Occasionally, the same Relic is available as both a Daily Power/Event Relic and a captured Relic at the same time. In that case, two copies of that Relic may be equipped at the same time, usually stacking their effects (some Relics do not stack when multiple copies are enabled).

Some Relics are only available as Event Relics in Contested Territory: Magic Monkeys, Military Monkeys, Primary Primates, and Support Simians.

Boss Rush

In Boss Rush, teams begin with one Relic enabled. After defeating each island, they gain access to an additional Relic for all the subsequent islands.
