Perma-Spike is the Spike Factory's path 3 tier 5 upgrade in Bloons TD 6. Spike piles are produced about 3.46x slower (without crosspaths, every 1.75s to 6.06s), but deal 10 damage, have 50 pierce (85 with 1-0-5), last up to 300 seconds, and carry over up to 3 rounds. Additionally, the 4x start-of-round speed boost now lasts for 10 seconds. Unlike other Spike Factories except its Paragon, spikes placed by a Perma-Spike are preserved when loading a save, though any buffs the spikes had will be lost.

Strategy
[edit | edit source]This section was last updated for: version 55.2
Perma-Spike is a very versatile T5 tower. It can serve as a perfectly consistent cleanup tower, leak-catcher and/or win condition for CHIMPS. Since the tower only cares about how much RBE it has to absorb, it is potent against DDTs and Super Ceramics, being able to handle every DDT through round 100. This also means that alongside being a DDT counter, Perma-Spike can also trivialise round 100 by exploiting the single BAD's relatively low RBE. Pair Perma-Spike with Stronger Stimulant, Abyssal Warrior, and Jungle Drums to improve its capacity. Overclock is another, more expensive option. If your strategy relies more heavily on Perma-Spike for general damage output, and not just cleaning up or answering DDTs and the BAD, use it with stalling towers; Horned Owl and MOAB Shove are the best, while Cryo Cannon and Maim MOAB require less micromanagement. It excels on maps where it can cover every exit, such as Glacial Trail and Workshop. On maps that Perma-Spike cannot reach every exit, such as Muddy Puddles, use the Reposition abilities of Support Chinook or Dan D'Monke. Smart Targeting is an inconsistent option for these maps, and another micro-heavy option is to repeatedly alternative between the "Close" and far "Set Target" targeting options to ensure spikes are balanced in each exit.
As a cleanup tower, Perma-Spike should not be solely relied on to tank most blimps from the dense lategame rounds like 96 and 98. However, it highly complements towers with high raw damage that also tend to leak Bloons. Unstable Concoction should be used if your strategy uses Perma-Spike, as it is cost-efficient extra damage, and its usual downside of leaving huge packs of MOABs and Ceramics is not a problem for Perma-Spike. For Heroes, Admiral Brickell, Corvus, and Ezili's abilities are good for cutting away large amounts of RBE from dense rounds. Benjamin is a niche choice; he can use Syphon Funding to drastically reduce the densest rounds, and it is this synergy with Perma-Spike being the primary reason to ever consider him in CHIMPS.
Perma-Spike struggles in Freeplay as it does not scale well with the increasingly denser rounds. Outside of standard gamemodes, its main use case is in Races, by using it to instantly pop the remaining Bloon spawns after the bulk of rounds have been cleared.
Both crosspaths are almost equally effective. 1-0-5 is slightly cheaper, has marginally better DPS (1.7× instead of 1.667×), and has the option of upgrading to 2-0-5 in Ice Monkey-centric strategies (usually for frozen Bloons; Lead Bloons aren't a concern unless Acidic Mixture Dip isn't available) for the same overall cost as 0-2-5. 0-2-5 benefits slightly more from flat pierce buffs, including 
One More Spike; if Perma-Spike has Stronger Stimulant supporting it, 0-2-5 has slightly more DPS than 1-0-5, assuming the Alchemist can maintain enough uptime on it with the brew buff.

“
Like a few other towers before it, the attack speed crosspath for Spike Factory has outshined the others. We have reworked the lower Spike Factory tiers to distribute this power more evenly while keeping high tier factories at a similar level of power.

In addition, Permaspike’s neglected crosspath has had a small pierce increase as currently their only real use is under custom challenge rules.

Smart targeting now places spikes as far back on the track as it can, rather than directly in front of the Bloon closest to leaking (undocumented)

Some minor changes to a few upgrades on Spike Factory evening out some aspects of it.

- Spike per spike pile reduced ― 90 → 45
“
Finally, we enjoyed the hard hitting nerf to Permaspike’s early game, but admittedly this change didn’t really change much of anything for its endgame power while impacting pre r80 rounds far more, so we’re redoing the nerf into a pure attack speed nerf along with an increased benefit to the start of round rate buff to reduce the necessity in playing slowly with it

- 1-0-5, 2-0-5
- Pierce increased ― 45 → 90
- Spike Factory no longer can shotgun spikes for exactly one frame after spawning (bug fix)

Permaspike is seeing a small crosspath fix, as the x2x rate change threw this balance out.

“
This update we’ve finally decided to nerf Permaspike by completely removing the ‘Far’ target priority from the earlier Smart Spikes upgrade. We know that this loss will be incredibly painful to deal with for the many spike factory enjoyers out there, so we have also included a couple other minor QoL adjustments to the Smart Spikes upgrade in a hopeful attempt to offset this.

- Reworked targeting options ― Normal, Close, Far, Smart → Normal, Close, Smart, Set Target, Automatic
- Smart Spikes: Adds a "Set Target" option, which allows to select the place inside the Spike Factory's range where the spikes go to.
- Smart Spikes: Adds a "Automatic" option, attempts to directly target the first bloon
- Removed "Far" targeting option
