I'd like to highlight this absolutely incredible invocation and just can't recommend it enough!
Of course, an invocation is always a very personal experience that can be different from person to person.
Now, all of this is my own experience and I'm in no way generalizing it for everyone. But I'm sure others will find a lot similar things.
Although it's name brings it precisely to the point, there is a lot to it that one might not think of when referring to intelligence.
When I activated this invocation for the first time, I was shocked when, sitting in a meeting, I was able to follow two different conversations on the topic, take part in a private conversation next to me, write the protocol of the meeting without missing anything and translating a piece of book. That took multi-tasking to a different level.
What I personally experience every time is my awareness and focus changing to laser sharp. I see and hear my surroundings differently. My reflexes are enhanced. My coordination and speed are improved. My empathetic skills are refined and don't overwhelm me. And so much more! It's really like unlocking new brain areas.
This invocation may also be very interesting when dealing with ADHD, as Glasya can help improving mental health and stability.
On top of all that, there is the second, one day invocation that this piece comes with, that will give you an enormous advantage when hexing, not only making it more powerful when having your enemies knocked off their feet with snipersharp precision but at the same time staying safe and unseen, too.
For me, this invocation is an absolute must-have I can't recommend it enough!
If you don't have it, yet, I'd definitely suggest considering it! Chances are high you'll love it as much as I do. ☺️
