I have a group of players that include a bard who can use Weird Words. They are about to fight a boss who has a thundering weapon. Can I have the boss' spellcaster cast Silence on the boss, negating the bard's attack and have the boss still use her Thundering polearm?
Silence spell: ...Items in a creatures's possession or magic items that emit sound receive the benefits of saves and spell resistance...seems like yes, however(at least how I'm used to it) a willing subject forgos their saves and spell resistance to allow the spell to work on them. So if the boss doesn't try to fight the spell then I don't think the weapon will work. Though I'm not entirely sure.
