How does Geas/Quest interact with sleeping targets, and when cast with metamagic silent-spell?
Recently I have begun to look at the Geas/Quest spell in Pathfinder, both for potential use as a GM, and as a player.
Now, the spell is language dependent, meaning the target has to be able to understand the caster, however does the command need to be issued vocally or is it transmitted mentally?
Ikbar the sorcerer has learned the Geas spell, and also has the metamagic feat silent spell. Geas/Quest only has verbal components, so by casting it with silent spell, does he then need to issue a verbal commmand, or are the terms of the geas transmitted mentally?
Furthermore, how would this spell affect a target who was sleeping? For example:
Isasneak the Bard sneaks off on his own to attempt to gather information for the party. They are in a castle, and while not regarded hostile, are still regarded with serious apprehension. He covers himself with invisibility and sneaks off. After sneaking into a room he finds the king taking a nap and casts geas on him because hey, why not. Bard shenanigans. Assuming the king isn't woken by the verbal components, will it still take hold?
Now, if you decided that it should be a mental transmission, assume the bard from case two first cast a zone of silence around him, and then cast the geas. He could still verbally speak the components of the spell, but zone of silence states that it disrupts language-dependent spells.
