Buying Supporter Packs

Hi. I've got "Path of Exile 2 Early Access Supporter Pack" and want to get "Lord of Ogham Supporter Pack".
1. Will I get a spare EA Key I can share with my friend while keeping all the cosmetics and coins for myself?
2. Any limitations with me already having a cheaper version? Like less coins or something?
Thanks in advance!

If you upgrade from the base supporter pack to the next tier you can see in the list what each pack has included. Everything with this greyish tone listed there is something you already got fully or partially (the points for example).

The base version gave you 300 points and the next pack says 600 points, but it mean "600 points in total", thus, 300 on top of you 300.

With your base version you bought PoE2 access for yourself OR you can get it as key for someone else, not both at the same time with this base version.

If you want an additional key for your friend you had to upgrade to supporter pack "Thaumaturge of the Vaal Supporter Pack" OR get another base one, I guess.
Like... buying the game for a friend shouldn't be that complicated.
