A repetition/expansion on an unanswered question from the last thread:
Q23a: Can a Spellguard of Silverymoon's Selective Spell ability be used in conjunction with long-duration BC effects, such as Freezing Fog, thus allowing (in this example) selected creatures to see and move through the Fog unimpeded?
Q23b: If this is the case, can said Spellguard designate their own type/subtype as unaffected by, and thus be able to cast within, their own Antimagic Field?
