Almost every game except PvP has a shop where you can buy permanent upgrades which help you in-game. PvP shop may contain things like "Spawn with a golden apple in FFA and Assassination" or "Upgrade Insane Duel TNT kit". There would be 4 sections to the shop: Duels, FFA, Assassination, and FFA/Assassination.
Duels would have things like upgrading kits. You would go into the duels upgrades section, then select a type (Overpowered, 1.8, Normal, Insane), and select a kit to upgrade. Insane duel -> TNT would contain upgrade to tier II such as leather pants -> golden leggings, tier III would make the boots iron, tier IV would make the helmet gold, etc. Explosive bow might add power to the bow so that it would deal more damage for tier II.
FFA section would make things like an extra sharpness level to each sword, faster elytras, etc.
Assassination section would include things like lucky chests (Gives more money per chest), cheaper store (Makes things 5% cheaper per level in the store), or slower store hunger (1 second longer for hunger to start going down quickly in the store).
FFA/Assassination section would be general FFA stuff such as golden apples on spawn, unlock better spawn points, etc.
Duels would have things like upgrading kits. You would go into the duels upgrades section, then select a type (Overpowered, 1.8, Normal, Insane), and select a kit to upgrade.
