With no separate spells for flight form or aquatic form it no longer appears to be possible to apply or remove glyph of the aerial chameleon or glyph of the aquatic chameleon. they are still working if you had them applied before the pre patch.
as it turns out… i had ‘hide passive spells’ checked in the spellbook. when i unchecked it the aquatic form and flight form passives become visible and vanishing powder can be used on them
