The reason I like linking the number of amulets/rings to willpower/intelligence is:
- Physically, there is no reason to limit the wearing of jewelry (see Mr. T, as above)
- Balance-wise, there is a reason to limit the amount of jewelry.
So, tying it to a relevant stat makes good gameplay sense. If you want to wear lots, you have to craft your character accordingly. Also, it makes some realism sense, in that you have a limited amount of magical aptitude, so to speak, and so are unable to equip that extra enchanted item.
Ideally, your stats would limit the
absolute number of enchanted items equipable. Or, more elegantly, limit the number of active enchantments, while stll allowing unlimited physical wearing of jewelry. You can put that next ring on, but the enchantment won't go into effect.
