How to use Energizer

Energizer is the top path tier 5 Monkey Sub, and it is a support tower first. While submerged:

  • Every ability on screen recharges 20% faster. Water towers in its range get 40% instead.
  • Heroes in its range gain +50% XP from round ends and sacrifices (not from buying levels).
  • The de-camo and damage pulses gain 1,000 base pierce, and the damage pulse deals 5 damage with +5 against Ceramics.

When not submerged, its darts deal 5 damage instead of 2.

When to buy it

Energizer's value depends on the mode:

  • Freeplay and Boss Events: its strongest use. The cooldown cut is essential for ability towers like Ultraboost and Homeland Defense, and it also speeds up money-making abilities while you farm.
  • Normal games and CHIMPS: mainly a hero-leveling tool. Slow-leveling heroes such as Admiral Brickell, Psi, Captain Churchill and Sauda reach higher levels before round 100. Brickell is the standout pairing, since her water abilities get the full 40% cooldown cut.

The tower cooldown buff alone is usually not enough to justify Energizer outside Freeplay and bosses.

5-0-1 is the preferred crosspath. Faster pulses clean Super Ceramics better, while 5-2-0's Lead popping and pierce add little.

Keep in mind that building the Monkey Sub Paragon absorbs every Sub on the map, Energizer included. Submerged, the Paragon takes over this support role.

Is it worth it?

For Freeplay, boss events and hero-focused builds, yes, it is one of the best support tier 5s. As a damage tower it is weak, and in a normal game you should only buy it for the hero XP or a specific ability-based strategy.
