Heartless is a Relic in Bloons TD 6. It reduces the regrow rate of all Regrow Bloons by 10050%, effectively making them regrow a layer every 301.5 seconds. It stacks multiplicatively with itself if used as both a Team Store relic and a Tile relic.
It is essentially a weaker version of Broken Heart, but still provides the same value of eliminating Regrow farms, saving cash in Least Cash, or performing a difficult saveup like Special Poperations.
Unlike Broken Heart, Heartless works on DoTs like Corrosive Glue, allowing some niche in Time Attack tiles when using Glue Strike.
Having both is not necessary, as they both accomplish the same purpose in different ways.
