Trident Swiftness →

Trident Efficiency is the Mermonkey's path 1 tier 1 upgrade in Bloons TD 6. It reduces the attack cooldown of the Mermonkey's trident attack by 20%, increasing its attack speed by 25%. It also increases the pulling rate of the trances of Alluring Melody and above by +11.11% (attack cooldown reduced by 10%), but does not decrease the downtime of the trance. It has no effect on the Arctic Knight's Ice Jet ability.

Strategy

This section was last updated for: version 52.0

Trident Efficiency is rather weak for a lower-tier Mermonkey, which is often less effective than buying a second Mermonkey. Hence, this upgrade is usually bought as a crosspath, especially for higher-tier Mermonkeys. It's still useful for a minor speed buff to lower-tier Mermonkeys. It's less effective than Sharper Prongs in Race conditions but still the best crosspath for an existing 0-1-0 Mermonkey.

Last update many players felt blindsided when Brickell stopped applying her buff to Mermonkeys since there was no mention in the balance changes section. We would like to apologize for that - it was tasked internally as a bug as it was indeed unintended to work that way. We then left the issue alone for a long time, mostly due to other more pressing matters, and this issue fell through the cracks. In retrospect, it would have been better to treat this as balance rather than a simple bug fix due to how much time had passed. Reading through your feedback, we did consider just reverting the change, however the bigger issue that the feedback reinforced to us was that players considered Mermonkey to be so bad that it was only a "good" tower when used in combination with a single, water-only hero. This sort of forced synergy goes against our design intentions - namely that Mermonkey being our signature amphibious tower should be able to stand on its own without being balance-locked to an interaction with a single hero. With all that in mind, we feel Mermonkey's highest priority right now is large sweeping buffs to each of the paths, so most of the following changes are our first step towards this starting from the low tier crosspaths.
