One More Spike

"Spike Factory stacks get +1 spike"

- In-game description

One More Spike is an upgrade in the Support Monkey Knowledge tree introduced in the initial version of Bloons TD 6. Once One More Spike is activated, all spike piles generated by a Spike Factory regardless of it's upgrades have +1 spike. One More Spike has no other additional requirements, however the player still needs at least 1 Monkey Knowledge point to activate.

Summary
One More Spike is one of those small stat increase Monkey Knowledges' that allows the Spike Factory to have piles last a tiny bit more. The Monkey Knowledge is more of a stepping stone to the more better Monkey Knowledge as One More Spike is more of a situational kind of thing.

Tips

 * This may be useful in challenges involving the Spike Factory, if Monkey Knowledge is enabled that is.
 * Upgrades like Perma-Spike and Spike Storm/Carpet of Spikes are affected by this Monkey Knowledge, which can make them perform just a bit better.
