I have indestructible harvesting tools (perfect investment of gems, for anyone contemplating buying them) and they have remained glyph-less since I purchased them. Today, RNG was finally on my side and I got a glyph of the unbound for my tools. I could have sold it for 140g according to current market prices, but instead I decided to use it. These reward the currency from season 3 and are something I own very little (if any) of. The rewards include things like miniatures and ascended accessories, so here’s hoping it comes in handy for me! Now I just need two more glyphs to round out the collection..
