I'm going to the store. I need one loaf of bread however the bread is connected to another piece of bread so the price is increased but I only need one!?
Well this is what the suggestion is about.
Allow us to buy one weapon slot instead of two weapon slots for a decreased price. Two weapon slots cost 250 energy crystals, but one weapon slot will cost 175 energy crystals.
That's the end of the simple suggestion.
Since when did the devs decide to implant this? I think the energy depot is fine in selling the weapon slots. We need energy sinks and I don't know where you got the idea of "No, you can't buy 1 weapon slot" because you get 2 free weapon slots that are permanent in your knight
