OOC:
Just a couple quick notes.
When I call for a roll, that is because there is risk and uncertainty. In many circumstances, it is truly success/fail (e.g. in combat; you hit or you don't). However, when things are free-form, then the reading of the dice is more flexible and helps the GM determine how to guide what follows. Just because the dice roll is a failure doesn't mean what you are trying to do is utterly failed in the worst possible way. (Well, roll snake eyes, and, yeah, that's not good. Roll box-cars and it will ludicrously bend in your favor. Everything between is nuance.) Instead, it gives the GM guidance in how to handle that situation.
Also, if you think you should have advantage on a roll, always call that out and say why. It could be magic, circumstances, background, trait, whatever. I do not promise to accept the reason and give the advantage, but you think there is a legitimate reason why you should get advantage, never hesitate to ask. Just remember there has to be a reason for it. Just like if I pull disadvantage on you, I have to tell you why. I may need to wait to explain why, but I should always be able to say why.
In this case, we'll stick with the roll as it. Don't worry, it isn't fatal or anything.
Also, state whether you are giving Ishzu his chance or not.
