on act 4 and on the first summoning room. Ive collected my spider leg, kohar root, feynur potion and my wisdom rune, but the teacher says im still missing some components, I've tried putting all the stuff in the circle and talking to the teacher but still same old, u are missing some components, god damn it its frustrating
This is a known problem. Drop everything (and I do mean everything: spider leg, kohar root, feynur potion, my wisdom rune and THE BOOK OF BASIC SUMMONING) not in the summoning hall, but further away (lvl 2 entrance hall is fine) and pick it up again.
Now go back to the summoning hall (if you're ok, your exp should go up as soon as you enter the room. Talk to the summoning instructor (she'll take the rune and tell you to put the other components in the summoning circle). Listen to her!
(Did you drag the summoning book to your inventory? I think that may be the cause of the problem...)
