Very Shreddy

Very Shreddy adds +1 damage against MOAB-class bloons to every spike made by a MOAB SHREDR Spike Factory (middle path tier 3) and its upgrades. That includes the spikes from Spike Storm, the spike storms from Carpet of Spikes, and Carpet of Spikes' constant spike rain. It is a fourth-row Support knowledge that needs 3 points in Support and First Last Line of Defense, plus a one-time fee of 250 Monkey Money.

How it changes the game

MOAB SHREDR spikes already deal heavy bonus damage to blimps. Very Shreddy adds one more point of damage per spike that touches a blimp. Because a Spike Factory produces piles all the time and every spike in a pile that hits a blimp gets the bonus, the extra point adds up to a solid increase in blimp damage, roughly 10% more per SHREDR spike.

Where it matters:

• Last-line blimp defence. A x-3-x or x-4-x Spike Factory placed at the end of the track to clean up MOABs and BFBs that slip through gets a little more reliable.
• Spike Storm and Carpet of Spikes. These abilities and the tier 5 constant storm cover the whole track with SHREDR spikes, so every spike gets the bonus.
• Deflation and freeplay. Spike Factories that do a lot of the blimp work benefit most.

To get the most out of the bonus, use a crosspath that makes more spikes, usually 1-3-0 or 1-4-0, since the top path adds spikes per pile. The bottom path does little for SHREDR damage.

It does not affect the Spike Factory paragon, the Mega Massive Munitions Factory. In the early game it does nothing, since you will not have a MOAB SHREDR before the first blimps.

Is it worth it?

Priority: situational. It is a nice upgrade for players who rely on Spike Factories for blimp damage, and almost irrelevant for everyone else. Its second job is to unlock Hi-Value Mines, which takes $1,500 off Spiked Mines.

Compared with the other fourth-row Support knowledge, it is one of the weaker choices. Most players should get Backroom Deals, To ARMS! and Inland Revenue Streams first.

Where it works

Very Shreddy works in all modes with Monkey Knowledge enabled, including Deflation and Impoppable. It is off in CHIMPS, so SHREDR damage there is the base value. Challenges with MK disabled and Rogue Legends also ignore it.
