the rune of spellweaving is stated on the website to work with turn undead. through some testing it doesn't seem to work. I get a chat message regularily when casting direct damage spells stating that the rune has activated - even when it doesnt double cast (if monster dies on the first spell) i still get the message. when casting turn undead i do not recieve such messages.
suggestion - give chat notification even when tu is successful to show that it is activating.
suggestion - if rune activates on successful TU have the extra spell activation target a nearby eligible target
