Hi, I can't seem to be able to do it by myself so now that there's a new update I'm going to ask for help, I also looked into the game guide, Gallery #5 that says Win to Bulls (>=7 END) I can't seem to be able to get it I always get the <7 and I'm pretty sure I won more than 7 times by now haha. P.S: I'm in the Neutral Route with Thane 
EDIT: Forget it I'm stupid I was reading END as in the word not Endurance... can you see that I go for INT, AGI and CHA? XD
EDIT 2: The Incense was worth it... (^///^)
