Diablo 4 item upgrader Upgrades
Item upgrades allow players to raise the level of equippable items such as weapons or armor, as well trinkets up to a certain amount. You can upgrade items at any NPC that accepts the appropriate currency.
Upgrade components are slotted into equipment to provide bonus effects and attribute bonuses. These are usually slot-restricted however, there are some universal upgrades.
Rerolling
A player can reroll an item upgrade in Diablo 4. This is done through the Level Up feature, which stops your game and shows four randomly chosen upgrades. The player can choose one of the upgrades to continue the fight. The cost of rerolling is similar to a normal Level Up. However, players must be careful when selecting an upgrade since they won't know what the new stats will be until the item upgrader kit is being rerolled.
The Best item upgrade's rarity and tier determine its upgrade. Each level of an upgrade boosts the power of the item by +3.
