We got heard on the lammania forums , they have now fixed the aura´s randomly healing value, and you can now attack physically too while its active without stopping its pulses =)
They will try and get the bug fixes into update 5, and if they dont manage it, patch it in after release most likely in the first hotfix/patch.
Sweet, time to level my TR cleric up to 20 so I can TR again and have some outrighteous fun from 6-20 levels
