I'm currently able to alchemy, both low and high, for free. No runes necessary but I do not receive any xp gained from doing so.
I just alched 100 items and received the gold.
Long story short, my bank is full. I went to sara, came to g.e. to bank after the trip. I deposited inventory/worn items into bank. I was not able to deposit everything. To be exact I had 2 peaches and 2 saradomin swords that I had brought back from sara still in my inventory. I went to the dentist, came back and am getting ready to do wildy diary and noticed I need alch runes. I looked at my mage book and noticed the spots for Low/High alch are clickable and working, but the req runes are at 0/1 nat 0/5 fire.
Did I discover an Alchemy glitch? I had runes available in the rune pouch for both B2P and Alchemy prior to banking but only the Alchemy spells are available to do this with apparently.
