I've really enjoyed the game. However, I did want to alert you to a (strange) bug/crash that I've encountered (Win 11).
If the Mage casts "Multiple Shock" while equipped with the "Great Lightning Staff", the game silently crashes to the desktop. I've tested this across different enemies and in different zones and it appears to occur every time. No crashes occurred when casting spells other than Multiple Shock (including, e.g., "Ice Wave" and "Yellow") while equipped with the Great Lightning Staff. There were also no crashes when casting Multiple Shock while equipped with other weapons (checked specifically with the "Sinister Staff" and with the "Staff of Light").
