I do not know the spell blocks of any of the jinxes in this chapter, but will appreciate help and information regarding them from anyone who already knows or gets to know anything about them. This is because you can make out that these spells can be very useful in duelling, and are helpful to know about, as they already exist and so that atleast you will know what it is if you or someone else gets hit by one of these, and knowledge of spells is very important in duelling and in the wizarding world in general.
