Wave Mistress

The Wave Mistress is a special agent appearing in my conception of BTD6. She can only be placed on water, and attacks bloons with balls of water, that pops two layers, and slows them down to 75% speed. The water balls splash into a 0,1 Bomb Towers burst radius, which pops one layer of bloon. She costs 250 MM.

Pro
The Pro version throws larger balls, that pops four layers, and 2x faster. It is unlocked after 40 times. The balls explode in a Big One's radius and do 10 damage to Ceramics. The Big One-like explosion pops 2 layers, and do five damage to Ceramic Bloons!
