Strange question I know.
But I was just wondering about using shadow conjuration greater to create a bridge by mimicking wall of stone. It's instantaneous and effectively permanent.
My character can auto-fail his save and walk over it with ease.
But can I voluntarily forgo my spell focus, cha bonus and the like to make the save really easy? If the army of orcs following me make their saves, 40% of them won't be affected by the bridge and won't be supported?
