The first step to interrupting a charging Mongrel is to unlock the Edurus Potion. This powerful potion is acquired by completing the Potions Class quest, which will teach you how to craft the potion using Ashwinder Egg and the Mongrel Fur. Professor Sharp will guide you throughout the process.
The Ashwinder Egg is a valuable item that can be found in the Forbidden Forest or East of Hogsmeade. Once you have the Ashwinder Egg, you will need to find the Mongrel Fur. Defeating a Mongrel will reward you with its Fur, which can then be used to create the Edurus Potion.
The Edurus Potion is a powerful concoction that will boost your defensive stats against enemies. Drinking the potion will also increase your chances of surviving a direct confrontation with a charging Mongrel. It is recommended that you drink the potion shortly before any potential confrontation with a Mongrel.
When you come face to face with a charging Mongrel, it is important to be ready. Your offensive and defensive stats should be at their highest, so be sure to take the time to boost your stats with the Edurus Potion.
In addition to the Edurus Potion, it is important to know the Mongrel’s weak points. Mongrels have a vulnerable spot just under their belly that can be exploited with an attack. If you manage to land a critical hit in this spot, you can interrupt a charging Mongrel’s attack and buy yourself some time.
