/onlineSets your status so guildmates see why you are not answering. /afk takes an optional message, /dnd suppresses incoming whispers entirely, and /online clears both.
Writes a system message that only you can see. Trial groups use it as a pre-pull checklist — food, potions, mundus — without spamming the group channel.
