I dont know if this has ever been addressed before, but i was looking for a rational explanation of it in the PHB (3.0 and 3.5) and cant find one.
The shields in D&D are assigned arcane spell chance failure numbers, as is armor, which represents the way it hampers movement and somantic components during spell casting. Rules for casting say that as long as the caster has at least one hand free, they can cast spells with somantic components. Having only one hand free does not as near as i can find, prevent or penalize any spellcsating, so why would using a shield in one invoke a penalty. The regular penalty for not having the right shield feats would still apply. Does anyone know where i might get clarification on this, and does anybody have an opinion as to how that might affect game play if i were to revoke the spell failure chance on shields?
