Relic Knowledge

All Relics collected in the first CT, with exception of: SMS, Air And Sea, Monkey Boost (Note: this is pre-33.0 UI menu exterior)

Relics are in-game modifiers on Contested Territory and Boss Rush in Bloons TD 6. By collecting relics, they unlock special game perks via Relic Knowledge. Relics can be earned by capturing Relic Tiles, which earn Map Relics, or by purchasing a small selection of available Daily Relics at the Team Store. Collecting a Relic allows the team to choose up to 4 Relics from the pool of captured Map Relics and up to 4 Relics from the selection of Daily Relics.

Relic Knowledge is kept if and only if the particular Relic is still available. This means that any team that loses control of a Relic Tile will also lose the associated knowledge that goes with it until the team captures that tile again; the same also applies with neutral tiles. Any team that fails to capture a tile when it turns neutral will also lose the knowledge until it is captured again.

Some of relics can stack quantities or effects via both the Store Relic and captured Map Relic of the same type (e.g. stacking a Powers relic will double the amount of that Power).

Strategy

Summary

Relic Knowledge is vital for the top success in capturing tiles. Each one of them provides a notable benefit for all tiles, especially Banner and Relic Tiles. Relics can be used on any tile, and can compensate for the lack of some Monkey Knowledge. Strategize how each Relic should be earned in a specific order, and use the benefits of each Relic to obtain minimal scores and conquer particularly challenging tiles.

Tips

• Start with the closest Relic Tiles first and then travel outwards to capture the powerful Relics. The Relic Tiles available close to the team's home tile can give some benefits for capturing future tiles further out.
• If there are 4 or less Map Relics owned by the team, use them all for the maximum advantage. If there are more than 4, choose the best 4 Map Relics to use for conquering tiles.
• Try to buy the Daily Power if possible unless it does little to no effect (Tech Bot being a notorious example). Almost all Power Relics have at least some use that may help maximize your advantages in optimizing scores.
• Remember that it is not possible to opt out of any bought Store Relics. Some of these may backfire, such as life-regenerating Relics (such as Restoration) when using Heart of Vengeance strategies, though most bought Store Relics overall are a major benefit.
• Store Relics and Map Relics of the same type can stack. For instance, unlocking the Road Spikes Daily Relic and capturing the Road Spikes Relic Tile unlocks two instances of the Road Spikes Relic that could be used and stack upon each other. It is not confirmed whether all types of Relics stack, but some Relics can't stack most or all of their effects. Example of a specific interaction: e.g. Restoration's regen stacking with itself but not max lives.
  • All Power Relics can stack in that the quantities stored is doubled.
  • All Relics specific to damage bonuses do stack with itself and other Relics.
  • It is not expected that discount-specific Relics stack with themselves but do stack with other Relics (e.g. Air and Sea + Military Monkeys for a Monkey Ace, but not two Air and Seas).
• Ezili's sacrificing of lives via Sacrificial Totem do not affect the regeneration of lives from Restoration or Regeneration, provided no bloons leaked on the same round.
• Some Relics may have little or no strategical purpose for capturing tiles. El Dorado and Tech Bot are among the least effective Relics for those purposes, although El Dorado affects in-game currency and Tech Bot merely assists in automating user input.
  • If there are Relic Tiles containing Relics of insignificant value, don't be deterred by them; treat them as Regular Tiles with the difficulty of Banner Tiles but only half the score. Capture these tiles if the opponent may get an advantage of them, such as if such tiles are near "good" Relic tiles.

33.0

“	Most balance time this update was dedicated to actual towers, but a few Relic Knowledge points in CT stood out to us as far too strong or weak & are seeing the numbers update below. In future updates we will be taking a closer look at top & bottom performing relic points, so if you want to have your voice heard on that matter the next month will be the time.	”
	~ Ninja Kiwi

33.3

34.0

“	A small list of number changes have been changed up for CT Relic Knowledge. We are mainly here hoping to create a standout use-case difference for Restoration & Regeneration rather than one being purely better in every way.	”
	~ Ninja Kiwi

• MOAB Clash: reduced from +3 -> +2
• Regeneration: restore lives/round (up to starting lives) 10 -> 20
• Restoration: restore lives/round (up to starting lives +200) 20 -> 10

42.0

“	We’ve included slight tweaks for a few relic knowledge. Many of these relics are having slight number increases as they seem to have low value across all tile types (relics with low usage only on some tile types have not received changes as they still have value in niche cases), Restoration maximum barrier size is being reduced slightly as it too effectively acts as a complete camo counter in many cases while also providing benefits against non-camo Bloons.	”
	~ Ninja Kiwi

• Hero Boost: Hero XP multiplier increased from 15% to 20%
• Broken Heart: Bonus damage to Regrow increased from 1 to 2
• Going the Distance: Range bonus increased from 20% to 30%
• Fortifried: Bonus damage to fortified increased from 1 to 2
• Restoration: Maximum barrier reduced from 200 to 150

43.0

“	Minor tweaks to Heartless which feels it has no competitive edge over most other Relics & Monkey Boost which overperforms on all available tiles.	”
	~ Ninja Kiwi

• Heartless now ‘disables’ Regrow Bloons: Regrow rate increased 150% > 10,050%
• Monkey Boost granted uses of the Monkey Boost power reduced 3 > 2

“	Some Relics required more functional changes. As more range is situational and sometimes detrimental Going the Distance has been merged with Durable Shots to also grant increased Lifespan, Durable Shots now instead increases the pierce of all towers. As ‘Popping White Bloons’ is also far too situational Deep Heat now also grants Frozen Bloon popping and improves the duration of Freezes.	”
	~ Ninja Kiwi

• Going the Distance now also provides Lifespan +30%
• Durable Shots no longer grants increased lifespan
• Durable Shots now grants towers increased pierce +25%
• Deep Heat now also allows all attacks to pop Frozen bloons
• Deep Heat now also grants Freezes longer duration +10%
• Deep Heat now also allows Freezes to last extra layers +1

Trivia

• Some of the Relic Knowledge Points involving bloon type popping power tend to involve mixing damage types (e.g. "Alchemist Touch" for popping Leads, and "Sharpslosion" for popping Blacks).
• Only 8 out of 14 Powers are involved in Relics.
