Specific Class Guildhests
If you play for long enough, you're bound to run into someone who has no idea what they're doing and its painfully obvious. Bards using quick noch on a boss, summoners casting ruin without dots, white mages spamming holy to the despair of their mp bar with no lucid dreaming in sight.
I think if a level 50 Guildhest was automatically unlocked upon reaching level 50 that gave either glamor or a class weapon, we'd have a way to teach the basics to those who have no idea what they're doing whether or not they used a jump potion for an unplayed class.
