@ukku is this the first time you played D3 ROS?
Just in case your answer is yes, Legendary gems are for rings, amulets and weapons ONLY.
Gem of ease (GOE) is for weapons, even if dual wielding, only one GOE can be equipped per character.
Example, main hand weapon has a GOE in it and off hand has a GOE in it, only ONE of those weapons can be equipped till u remove a gem from one of them.
