The Final Harmonic
The Final Harmonic BTD6 guide: trance BFBs and ZOMGs anywhere on the map, hero and Magic buffs, Echosense range and best uses.
This elder can echo its irresistible tune anywhere. While devastating to Bloons, the call inspires nearby Heroes with improved range and cooldowns, and Magic Monkey's extra pierce.

How to use The Final Harmonic
The Final Harmonic turns the trance into a map-wide tool. The totem can now go anywhere on screen, the trance cooldown drops to 3 seconds, and the damage-over-time detonation cap rises to 10,000. The trance can pull BFBs and ZOMGs as well as MOABs and DDTs. Against BADs and Boss Bloons it cannot pull, but it still strips camo and detonates damage over time. Range grows from 32 to 38, and trident splash pierce doubles from 9 to 18.
It also adds a buff in the totem's range (or the Mermonkey's range without a totem): Heroes get +15% range and 15% shorter ability cooldowns, and Magic towers get +3 pierce.
When to buy it
At $25,000 it is a fairly cheap and reliable way to drag BFBs and ZOMGs into one kill zone, which is especially valuable on maps with separate lanes running at the same time. Place the totem where your strongest damage sits.
Stack Echosense Network with other Mermonkeys (for example a 2-0-5 Final Harmonic next to other Mermonkeys that also have Echosense Network) so the trance reaches every lane. The hero and Magic buffs help heroes that rely on abilities and Magic towers with low flat pierce, such as Druids and Wizard Monkeys.
Is it worth it?
Yes for late-game control in CHIMPS and multi-lane maps. It does not deal much damage on its own, so treat it as a support tier 5. Compared with Popseidon, it gives up raw damage for blimp control and buffs; compared with Lord of the Abyss, it suits Magic and hero setups rather than pierce-hungry Spike Factories. In boss events its buffs and DoT detonation on bosses keep it relevant.
