Hello, sorry but it is not guaranteed to draw an orange summon with a certain number of draws, there is only a chance to obtain one. Sorry for the inconvenience.

I'm sorry, it is hard to explain perfectly, there is no guaranteed amount of seal scrolls that gets you an orange summon, I say chance because most people do not get them within a set interval, when drawing 200 for a rebate, some people report getting no orange summons, while others report getting multiple. Some believe this is due to the inclusion of high leveled runes in the summon treasure.
