Shin had found himself in front of Professor Culloden office door, today Shin was here to ask the Professor a question to the Un-Felix Un-Felicis Potion. He was curious to trying to brew this potion but he had a rather odd question in regards to the recipe he had read it called for rose thorns have done some research he came across that though rose thorns were a common ingredient. It lacked some magical properties and its consistency was far to poor but it could be substituted with rose petals which properties were far better than that of the thorns he came today to see if there was any truth in this and if so could he substitute said thorns with petals. With a sigh Shin put on a smile and reached his arm up and with a slight reflex on wrist knocked on the door and awaited a response.
