I got into the sleeper temple by transforming into a meatbug, but ran out of transport to meatbug spells, but now it won't let me use any of my teleport runes (eg. teleport to necromancer, water magician etc.). I have easily enough mana points as only 5 points to use the teleport rune.
Is transforming to meatbug the only way to get through those iron gates in the sleeper temple?
