Perma-Spike

Perma-Spike produces piles about 3.5 times slower, but each pile now has 50 pierce (85 with 1-0-5) and deals 10 damage per spike. Piles last up to 300 seconds in a round and carry over up to 3 rounds, and the start-of-round 4x speed boost now lasts 10 seconds. Uniquely among normal Spike Factories, Perma-Spike's piles survive when you load a saved game, though any buffs on them are lost.

When to buy it

Perma-Spike is a versatile tier 5 for CHIMPS and standard play:

• It is a consistent cleanup and leak catcher at the back of the track.
• Because it only cares about total RBE, it handles DDTs and Super Ceramics well, and can hold every DDT round through round 100.
• It can trivialize round 100 by soaking up the single BAD's relatively low RBE.

Use 1-0-5 for the pierce boost, or 2-0-5 if you need Normal damage for DDTs and Lead without external support.

Good partners: Stronger Stimulant, Abyssal Warrior, Jungle Drums and Overclock all raise output. If Perma-Spike is your main damage, add stalling such as Horned Owl or MOAB Shove so the stockpile has time to grow. It works best on maps where it can reach every exit, such as Glacial Trail and Workshop.

How it compares

• Carpet of Spikes deals global blimp damage but struggles with density.
• Super Mines is a raw-damage monster at four times the price.
• Perma-Spike is the best value of the three for CHIMPS defense.

Is it worth it?

Yes. It is one of the most reliable tier 5s for CHIMPS black borders and an easy way to secure the late game.
