Obsidian corn seeds XXL

Obsidian product Main farm

The XXL seed only makes sense with a big stock of both the good and the manure at once, and because of the uneven jump in cost it isn't worth going into it piece by piece.

What it's for

These extremely powerful seeds are made on the obsidian farm and can be used on fields on your main farm.

Obsidian corn seed XXL is the strongest and at the same time the most expensive tier of obsidian seed for corn. Like the other tiers it's made in the Winter garden on the obsidian farm and used on the fields of the main farm. It isn't sold in the shop, it's the top of the crafting branch for obsidian corn seed.

How to get it

For 1 unit you need 45 units of a good from the obsidian farm, 4 Special corn seeds and 252 Obsidian manure, and production takes 2 hours just like the lower tiers. The jump is sharpest with that first good, which triples compared to the XL version, while the manure only goes up by half. The recipe is again identical on all Winter garden levels from 1 to 6.

What to do with it

The seed belongs on the main farm, where you plant it in any corn field, from the Field to the Spectacular field. Neither the recipe nor its uses mention any other outlet such as selling, processing, missions or the co-op.

Tip from a veteran player Before you queue the XXL recipe, recount your stock of that first good separately, you need almost three times as much of it as for the XL and it's easy to forget because the manure grows much more slowly.

Most common mistake People often estimate the cost of the XXL from the ratio between the basic and the XL seed, but that ratio doesn't hold for this good and the consumption is unexpectedly higher.
