Suggestion details: It would be nice if modpack maker could decide how hard will it be to level up the wand... Right now it is some difficulty or nothing (we can turn the progression off)... So if the difficulty could be tweakable by some config, it would be very nice.

Hmm this issue must have slipped through the net, sorry. It's something that has been discussed elsewhere though.

if spells are configurable and cool downs are set to high numbers it would take Super long to lvl up.

That's a good point. Conversely, if the costs were all made higher, it might be very quick to level up. For this reason, it does make sense to add this as an option.

I mentioned that in this post as well #235 thought that in the way it is set up right now I don’t think it’s too hard to lvl up wands as you get extra exp for discovering new spells and so on.

It only makes leveling additional wands up a bit harder but hey you are supposed to decide for one wand only anyway XD. But ye the adjustability of this number should be a thing like I mentioned in the post I linked at the very bottom here, if spells are configurable and cool downs are set to high numbers it would take Super long to lvl up.

+1 to this. Right now in my current pack it's infinitely less time to go mine a bit and just trade with a wizard till he sells a decent wand. Players are tending to just ignore wizardry for other magic mods, especially with the wand progress reset issues in the last ver.

Being able to config the wand xp rate would be really helpful to make it a viable early to mid game magic mod with stiffer competition present.
