Not played LS in over 7 years and I must be missing something.
Why can't I glyph my 2 magical rustad swords?
One has mana syphon and The other heal mastery.
The guide I read said The only req is that The items are atleast magical and that it can't have EE as The only stat.
So what kind of items can I glyph?

you can glyph 1 item per time not 2 in once!
you can glyph 2 glyphs with different stats on them and create one with having all stats in once!

Ah I see.
thanks alot for clearing up my confusion
