About Yurgimar battle...
Firstly, his attacks need to be a little more avoidable. First phase is good, but after 2nd Esper he just flying away after 1-2 hits, that makes him nearly impossible with his regeneration.
But in 2nd, I don't know about 1.9o (2nd time playing this map, at 1st time i was not able even for make him damage, and there was bugged espers o_O), but in 1.9q:
1. Sometimes it disables spellbook and potions for all battle. I think it causing by taking global cooldawn, when you defeating one of "corners" and taking "run timer" at some time.
2. Sometimes he just starting to burn your mana without stop. Don't think that this is normal, 'cause I don't see it every time I try defeat Yurgi.
Anyway, if both these "bugs" is normal, suggest you to give him ability to delete items from your inventory also
3. Please, increase colldawn of hero illusions he create, it's just impossible and unavoidable. I playing on EASY (!!!!) and I don't see any chances on
**** with this. I've killed EVERY boss without any death, but Yurgi has an abyss in difficulty between Zhi and Xire.
4. Also Jurxies has too long sleep duration. I just can't avoid any of Yurgi skills in 4th corner 'cause of 2 sleeping chars.
Really, this boss need much work, but it's nearly to be masterpiece
Seems, that Aero really like this character.
