wing: Right now, im thinking that players would prefer using dual wield weapons on lower levels so adding block bonus would make players think of considering shields, depending on their playing style (defensive or offensive). Also, a new shot bonus for bows and quiver may be introduced but not at 300%, say only 150%.

wing: Since there will be no restrictions on equipping, why not add block bonus on all shields. Block bonus grants the player to block a certain amount of damage received. Say 50% chance of blocking x% of damage received, where x varies with the level requirement of the shield (higher level shields blocks more damage).
