Gray Heron Takes Flight (unarmed skill) currently crashes the game if you use it. To fix it open manTemplateDB.xml in a text editor and find the line with "name="98"". Change "affectsPlayer="1"" to "affectsPlayer="0"". Edit: Actually, I noticed a few other spells use that template ID as well, so it would be safer to make a new seperate template entry for it and change its entry in spellDB.xml to reference the new templateID. Open manTemplateDB.xml. find the line with "name="98"". Copy those 5 lines (from template to /template), Paste it a line above. Change "name="98"" to "name="97""and "affectsPlayer="1"" to "affectsPlayer="0"". Open spellDB.xml and find the line with "spell name="Gray Heron Takes Flight"". Change "templateID="98"" to "templateID="97"".
Really? It freezes my game every time, I have to kill the process. Same as getting caught in the AOE of Handy wand/Psychokinetic Shove.
@Xidus That sounds like your files are broken, might want to vertify files via Steam. AFAIK, I've never heard of this bug before. And since you mentioned other spells, it more than likely is a corrupted file.
Yeah, I beat the game on Moderation with a unarmed/dual-shield build, and I used Grey Heron Takes Flight ALL. THE. TIME. It never crashed my game. Neither has using Telekinesis, either via Wand or the Spell. Backing up your save files and re-installing might not be a terrible idea.
