Myrrh gum is consumed to increase skill learning speed by 60%. Formerly, this sticky plant resin was ingested to actually increase the amount of skill learned per lesson. However, by decree of the Pentad, this efficiency became an inherent quality in all adventurers such that the herb's original property was rendered obsolete. In exchange, Kastalia, Goddess of Lakes and Rivers, and Melantha, Goddess of the Seasons, transformed myrrh such that it now promotes scholasticism solely in terms of learning rate. Important for brewing concoctions, myrrh also remains an ingredient in various elixirs, such as health.
