Popseidon

Popseidon's Ice Jet ability draws such power that a rogue wave floods the map with supercooled water, freezing all Bloons and reclaiming the weak for the sea.

← Arctic Knight

Popseidon is the Mermonkey's path 2 tier 5 upgrade in Bloons TD 6. Alongside a new separate Ice Jet ability that additionally summons a freezing wave, Popseidon gains two lateral tridents shot independently to the main trident, in an arc of 45° (60° with 0-5-1).

Both tridents do more base damage and MOAB-class damage, from 8 to 15 and +8 to +15, respectively. Base range also increases from 32 to 50 (40 to 62.5 on water). Popseidon's Ice Jet ability summons a wave that deals 70 to all bloons except those with Purple and White immunities, in addition to Ice Jet projectiles that do 30 damage instead of 20 and ignore all walls but also bounce off the edges of the map.

Strategy

This strategy section is empty or incomplete. See the strategy guidelines for more information on how to write strategy sections.

For its rather steep price, Popseidon is a powerful T5 that only has damage type issues and a lack of single-target damage. Due to its complete lack of White and Purple popping, it is more suitable for late-game when combined with additional defenses that can deal with Round 95's Camo Regrow Purple spam, because all its attacks are usually sufficient enough to clear out Super Ceramics and weaker MOABs and DDTs. Use its ability against a fast rush of bloons, freezing clumps while clearing out any excess bloons.

Both crosspaths are have solid use cases. The Trident Efficiency and Trident Swiftness upgrades provide maximum DPS but forgo the homing tridents, innate camo detection, and potentially massive range. The top crosspaths are preferred for reliable cleanup against dense clumps, but otherwise bottom crosspaths are more effective for general cases. Note that it needs camo detection to freeze invisible DDTs with the ability.

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 20 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. Popseidon had unintentionally more pierce on the central trident’s split projectiles, so this pierce is being spread out for a total increase. Finally popseidon released with a very wide projectile arc to prevent the seeking projectiles from clumping immediately, we like how this has worked out but feel that only the 052 crosspath needs to have this increased arc.

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.

•  Ice Jet: Projectiles pass through White or Zebra Bloons if they can't damage them, instead of destroying the projectile
•  Ice Jet: Projectile lifespan reduced ― 20s → 15s (undocumented)

2-5-0

  • Note: This means the maximum travel distance of Ice Jet projectiles is now the same as without the crosspath, since this crosspath increases their projectile speed by 50%

Middle path is seeing a consistency improvement for Freeze Duration & White Bloons, and Popseidon’s ability is being improved to damage & slow DDTs (if it can see them) and destroy all non-fortified Ceramics.

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.
