I kicked the statue "You stumble upon a statue. It is made of some unnatural watery substance which streams without losing its form. The statue seems to be vaguely familiar to you. ..."

Which gave me a corruption of living mana battery, but I am able to pick up and use wands freely. I don't know if it still confers over the 80% spell cost reduction (no spells with this character). I have save game backup if needed
