Tridents deal more damage, grow in power faster, deal bonus damage to MOABs and can now pop Lead Bloons but loses the ability to pop White Bloons. Gains Ice Jet ability - shoots a lot of ice balls quickly at the targetted bloon or at the target which can be placed anywhere on the map. Ice balls have a lot of pierce, freeze bloons and can hit the same bloon multiple times. The amount of ice balls can be increased by giving Arctic Knight attack speed buffs.

Version 44.1

“

While we’re not jumping into any full on balance changes, there’s a few corrections that we wanted to make for type-fixes and other intended play.
— Update notes

”

•  Ice Jet: Projectile lifespan is now capped at 15 seconds
•  Ice Jet: Projectile damage type changed ― Shatter → Plasma

Version 45.0

“

While the Arctic Knight has been popular, Riptide Champion has major pierce issues and is seeing a price reduction as well as a pierce increase to make up for this. Arctic Knight itself is receiving the brand new damage type added this update; as it is gaining a weakness to White Bloons from this and wasn’t too wild before we are increasing the power as well & allowing the ability to carry over 1 round to prevent projectiles timing out immediately when cast at the end of a round.

Version 46.0

“

While we were happy with Arctic Knight’s Ice Jet being a high pierce MOAB layer removal that could with other tower combinations be upgraded to a more effective full-clear, there is not currently enough varied ways of quickly dealing with White Bloon layers, so for a long cooldown based ability this heavy a weakness is too much for now.

Version 51.0

Mermonkey weren’t^[sic] feeling they favoured their natural habitat enough, so their Water Placement bonus is getting a boost. Middle Path Mermonkey just isn’t putting in the work we hoped, so we’re giving a couple price adjustments, a pierce increase across all tiers, and some light ability improvements to make it feel more rewarding.
