Well one thing is obvious, it is definitly a bug about the cap and if everyone wears those jewels there will be no point in using any magic anymore. This is an urgent one so please do fix it as soon as you can.
And about the Range beeing an advantage. i disagree. in order to cast you have to stop, So the range isnnt really an issue.
If you re doing an average damage of 150 per spell, and lets say you can cast 4 times before a melee gets near you you can do awesome dmg of around 600 hp. while the melee hits you once with his swords and does 1000. then you can start running away, but if you have to cast then you will have to stop again, while the melee will interrupt your spell and do another 1000 damage to you, while you can do another cast that most likely gets resisted and you will do NO damage, only 2 out of 10 spells will hit you. You know that if everybody will have a set with those resistances, magic will become useless. You just want melees to be strong and that no magic wont be any threat to you.
