Glyphs should at least be reworked. The concept of having attunement based effects on the utility spells is great, however most of them are quite insignificant. The heal is boring, summons are trash, condition based on attunement every 5 seconds should either have a shorter and stronger window rather than 30 seconds of meh and I’ve personally never used a single revive spell. The trait is also pretty weak and misplaced, since glyphs are kinda condition based, while the glyph trait is in air.
Another thing is summoned weapons. It’s not really a good idea to base an entire build to summoned weapons, since you’ll loose utility because of the attunement. Keeping the weapons, but making the summoning time shorter and not locking them to attunement would be a good idea, since it does not limit the elementalist. Also, having charges and a time limit is just a stressfull element. Remove one or another.
