Madscientist, i agree with you. Baldur's Gate is a high magical setting. But Sodark seems to enjoy more low to mid magical setting. I mentioned Gothic and Dark Sun because both games are not high magical setting like Baldur's Gate(they are no low magical setting like Conan or GoT where magic is extremely rare, ritualistic and generally comes with a lot of costs for eg)

About G1, among the prisoners on the colony, only one of then mastered circle 6 magic(Xardas) and only 2 reached circle 5(Saturas and Y'Berion), Corristo reached circle 4 and was the strongest FIRE magician in the colony(outside of colony, you have like 3 fire magicians with circles 4/5/6 magic on the entire colony), magic in Gothic 1/2/3 represents mechanic wise well the game world. And that is why is good.

Arcania in other hands is trash. Rune magic should't even work post G3 and it not only work but have cooldowns... The unique point that i disagree is

The answer is simple. Powerful entities don't give power or teach you for free. Tyr will require that you follow the DOGMA of his church to give divine spells to you. At the same way, a powerful succubus will require that you serve her and do her bidding to TEACH his secrets to you(a lot of people confuse clerics with warlocks, but clerics are a conduit to the God's power, Warlocks are apprentices to his/her patron). How you can serve both?
