physical/magic shields
game use general shield hp vs any dmg type, but why isn't physical/magic ones don't have unique mechanics attached to them to differentiate them from general shields, idea is:
- physical shield while its active not allow to steal/reduce hp, hp removal dmg type doesn't work. (pavice can protect vs Undying str steal)
- magic one while its active not allow to mana burn/reduce int/mana pool. (sky innate/glimmer vs manaburn)
