If you want to augment armor, the legendary gem you use must be at least rank 50.If you want to augment jewelry, the legendary gem you use must be at least rank 40.If you want to augment a weapon, the legendary gem you use must be at least rank 30.You should be taking your off stat gems (as in, if you are a Demon Hunter and don't use Topaz) and using Convert Gem to get them to your main stat type. These are the correlations for gems to stats: +210 Dexterity (Caldesann's Despair Rank 42) So, for example, let's say you used a level 42 legendary gem with an emerald, the added blue stat would be: The end result is a unique blue stat name on your item called 'Caldesann's Despair' (the name of the cube recipe for augmenting), as well as the rank and bonus to the stat. They are one of the keys to progressing into the upper greater rifts.Īs the accepted answer states, you get +5 for every rank of the gem. And you can add a different stat (needs gems ofcourse) than before as well (for example rings without mainstat you want to use on another class).These augments are extremely important for endgame content. Be careful since you can also use a lower level than you had used in the past. The new enchant will overwrite the old, so they don't combine. If you found the perfect item you can use a low level gem, and use a high level later for more stats. You can also overwrite the caldesann's despair effect with a new one. Once you can do higher grifts, you can continue on your levelled gems. This way, a new lvl0 gem drops and you can start upgrading that one. More tips: when you are getting low upgrade chance for your gems, 'hide' some in the inventory of another char. Please note that some gems cap out at 50, so don't invest in levelling those if you don't want to use them in your rings/amu. You get 5 stat points per level, and the type of normal gems determine the stat you get.

I think the question is related to caldesann's despair.Īnd the legendary gem does not matter for that.
