Glyph of Water Breathing
Your Water Breathing spell no longer requires a reagent.
An excellent glyph. I'm a huge fan of these no-reagent glyphs for obvious reasons. Although Shiny Fish Scales are abundant and cheap, they do take up bag space. What I like about these types of glyphs is that they'll literally pay for themselves over time because there's a direct cost. The best part of this? It now works exactly like the Warlock spell and can be used as an additional buff in PvP without worrying about running out of Shiny Fish Scales (e.g., it still consumes a reagent in Arenas).
