Living On the Edge

Living On the Edge is an achievement added in Version 21.0 in Bloons TD 6. To get this achievement, one has to complete a game that isn't Impoppable or CHIMPS with exactly 1 life remaining. Completing this achievement awards the player with 100 and a 0-0-2 Druid.

Tips

 * Ezili's Sacrificial Totem takes away 10 lives when used (1 at higher levels). This can be used without having to worry about leaking the wrong numbers of Bloons, or if Mana Shield's effect will absorb some of the life losses, since the totem will bypass the Mana Shield to take the lives.
 * Marketplace with the Healthy Bananas MK restores 1 life every round. Try specifically playing around with this MK to adjust the life count to a very specific amount.
 * The first round contains 20 red bloons. If timed right, you can easily pop exactly one bloon by placing a tower, which can be helpful with Ezili's totems. (You may need to disable Monkey Knowledge for the first round if you have Mana Shield)
 * Don't use Benjamin as level 6 Benjamin restores 5 lives at end of each round

Strategies
Strategy on 'Easy' mode without the Monkey Knowledges 'Mana Shield' and 'Pre Game Prep' (turn off Monkey Knowledge): leaking the entire rounds 4, 12 and 17 will reduce the lives to 200-71-80-48 = 1. If you have both Monkey Knowledges, leak rounds 3, 4, 6 and 8 instead.
