What I would like to see.
Additional slots for new items, such as:
-2 ring slots: Rings would give a bonus effect to offense, like a ring that lets you give fire damage to mobs you hit, or increase the damage you do per strike.
-belt slot: allows you to use belt buckels, these give you defense bonuses, like resistance to fire or explosions.
-amulet slot: Gives you varies effect bonuses, like increasing the drop rate of items, decreasing the ware the items experience, and such.
-2 trinket slot: These would be items that give random effects, like making certain mobs spawn less, allow you to see ore blocks, and other effects.
-packs slot: These would be different packs or bags that have different uses.
1) Back Pack: When worn, it allows you to carry 50% for items; would have a larger that holds double the items.
2)Bag of holding: Would function like a double-chest, allowing you to carry a large number of items while only taking up one slot in inventory; cannot be worn in pack slot.
3)Workbench Pack: When worn, it turns you 2x2 table into a 3x3 table.
4)Securi-Pack: When worn, it doesnt give any immidiate effects, but when you character is killed, all you items in you inventory (not hotbar or equiped) will be stored in a chest, simply breack the chest turn it back into the Securi-pack, and take back all your items.
-shield slot:When you have a sword (or other weapon, not tools) equiped, you can block attacks. All damage is negated, but the shield takes all damage, so it can ware down fast.
