Ok. Lot of itens working like flavor of time, occulus ring, nemesis bracer, but tyrael might not working it gives +10-20% damage to demons. I just tested and realzied it’s bugged. Can you fix it ? Thanks.
Stone of Jordan is it working too ? It appears not working.
If the item, equipped by your Follower, says “Emanates” next to the Legendary Power, that Power is given to your Character, like VitaKaninen stated. Think of it like equipping the Power using Kanai’s Cube.
All other Properties are to the benefit of your Follower. With Tyrael’s Might, there is no Legendary Power, so nothing “Emanates”. All of the Properties are to the benefit of your Scoundrel. However, since Followers’ Damage doesn’t mean much in D3, you will probably never notice the extra +16% Damage to Demons that he does.
Also, keep in mind that some items just don’t work with Followers.
There’s a lot of information about Followers on the internet, if you know where to look.
