Trial-and-Error is running rampant in battles due to no one knowing how many slots items are until you are in the equip screen, resulting in innumerable cases of undesirable purchases and character planning. We also have rampant cases where players spawn with a new weapon every round to see if it sheaths.
Let us take the guess work out of this, shall we?
This guide will be obsolete once the developers implement visible "Slots" and "Is Not Sheathable" into the buying guide.
If you wish to contribute, please do so as I encourage it and would greatly appreciate it. I do not want wild guesses, I only want input if you yourself have directly seen in the equip screen how many slots (0, 1, 2 or 3) an item uses.
