PHB 214
Light Shield: You need to use your shield hand to wield a light shield
properly. You can still use that hand to hold another item, to climb, or the
like. However, you can’t use your shield hand to make attacks.
Heavy Shield: When you use a heavy shield, you gain a greater bonus to your AC
and Reflex defense, but you can’t use your shield hand for any other task.
PHB217
Load: Ranged weapons that loose projectiles, including bows, crossbows, and
slings, take some time to load. When a weapon shows “load free” on the Ranged Weapons table, that means you draw and load ammunition as a free action, effectively part of the action used to attack with the weapon. Any weapon that has the load property requires two hands to load, even if you can use only one hand to attack with it. (The sling, for example, is a one-handed weapon, but you need a free hand to load it.) The crossbow is “load minor,” which means it requires a minor action to load a bolt into the weapon. If a power allows you to hit multiple targets, the additional load time is accounted for in the
power.
如果照上面对heavy shield的描述来看的话，是否一个人带了heavy shield不脱的话，在进行climb、swim等需要用到那只手的检定时，根本连投骰的机会都没有了呢？
按照上面的描述来看，是否可以认为如果装备小盾的话，副手可以用来拿off-hand的武器，但是不能用来攻击（交换双手武器算free action么？），副手可以用来协助装弹，而如果装备大盾的话，副手则不能拿武器，也不能拿其他物品，同时不能用来协助装弹（即无法装弹）么？
说我over interpret的同志认为，大盾的-2罚值已经代表了上面提到的那段话，因此带着大盾依然可以攀爬，可以游泳，只是要承受那-2罚值而已……
不知各位强者们如何看？
