In D2 Resurrected, if you want to upgrade a rare or unique item, you need to make a special Horadric Cube recipe. The recipe depends on the item you want to upgrade, but it will require a Perfect gem, these gems will not drop on Normal difficulty, you will usually find one at Hellforge. Or you can come directly to MMOWTS to buy Diablo 2 Resurrected Items you need.
In Act I on the Nightmare, they may drop randomly, but it is also impossible in the early stages. So to get the first random Perfect gem, you need to enter the game on Nightmare difficulty for a while.
When upgrading rare items or unique items, the modifiers remain untouched, but the base weapon will be upgraded from Normal to Exceptional, or from Exceptional to Elite, which means its basic stats will be improved. If these basic stats are subject to percentage-based modifiers, then upgrades will make a big difference. MMOWTS lists the recipes for upgrading rare and unique items.
