I've been off a few seasons I bought an ammy with (Allocates Heart of flame) But i'm not able to click on it to select it in my passive tree ( Requirements not met)

What am I missing here? I'm on pain meds but didn't think they were messing with me that much Lol.

you don't need to spend a passive point on stuff you've already allocated via external sources (gear)

The amulet has an anointment you get with 3 oils + cassia.
The passive is automatically applied when you put the item on.

you don't need to select it the ammy does it for you
