Diablo 4 Item Upgrades
The item level upgrade upgrade allows players to increase the level of their equippable items like trinkets, weapons, and armor within a certain amount. You can upgrade items at any NPC that accepts the appropriate currency.
Slots are used to add upgrades to equipment in order to gain attribute bonuses and additional effects. They are generally slot-restricted, but there are certain universal upgrades.
Rerolling
A player can reroll an Upgrade Item to an item in Diablo 4. This is done through the Level Up feature, which suspends the game and displays four randomly-chosen upgrades. The player can choose one of the upgrades to continue fighting. Rerolling is the same price as the normal Level Up. However, players must be careful when choosing an upgrade because they will not know what the new stats will be until the item upgrader kit is being rerolled.
An item upgrader kit's upgrades are determined by the item upgrading's rank and rarity. Each upgrade level increases the power of the item by +3.
