Enhancing to 12th star

[Illusion]

I used the search function, but I couldn't find anything about this.
My weapon has 11 stars atm and I'm trying to enhance it to 12 stars.

Does AEE have higher % of working than normal EE scrolls?
Tradable EE and AEE scrolls say it has a 10% chance of working, but untradable ones say 5% or lower which made me doubt.
Does anyone know more about this before I run out of wards?

Thanks

My understanding is that:

Regular EE: after 8 Stars the enhancement rate is 5%, regardless

Advanced EE: After 10 Stars the Enhancement rate is 5%, regardless.

I do not believe it should matter but dont quote me unless someone has a SS of a AEE saying otherwise.

Even if it's 10% it's not worth it, if you're using cash shop Shielding Wards.
More cost-effective to use that NX to cube your other gear, unless it's all godly already.

Nope, I had some untradable protection scrolls left.
Ran out, hit 0/47 EE scrolls .
