Kali Maaaaaaaa

"Gain 10 levels for Adora in one round"

- BTD6

 is an achievement in BTD6, introduced on Version 14.0. It can be achieved by leveling up Adora by 10 levels in a single round with the Blood Sacrifice ability (and not by manually purchasing levels). The round must be finished for the achievement to count. Earning this achievement will reward a Cash Drop.

Strategy
Using Adora's Blood Sacrifice ability, a tower worth $66,218 ($59,596 with the "Self Taught Heroes" Monkey Knowledge active) or more needs to be sacrificed to gain 10 levels assuming Adora is level 7 with no experience gained towards the next level.

The following towers can be sacrificed on Easy without MK to get the achievement:
 * Monkey Ace: Flying Fortress
 * Dartling Gunner: Ray of Doom, M.A.D, Bloon Exclusion Zone
 * Super Monkey: Sun Temple, True Sun God, The Anti-Bloon, Legend of the Night
 * Druid: Superstorm
 * Banana Farm: Banana Central, Monkey-Nomics, Monkey Wall Street
 * Spike Factory: Super Mines
 * Monkey Village: Monkeyopolis (with enough Banana Farms)
 * Engineer Monkey: Ultraboost

Trivia

 * "Kali-Maaaaa" is what the person who rips the sacrifice's heart out says in Indiana Jones and the Temple of Doom.
