So I just got an idea of a Harry Potter Mod Pack. It's not really a certain harry potter mod, but it feels like it is. So there are 2 Mods you need to download: (these mods are not mine) Instructions are in the page.
Alright now I will explain the features of this pack.
So the texture pack you added, it changes the bow into the texture of a wand. It also changes arrows to look like magic spells. The Elemental Arrow adds 5 more spells (arrows.) Here are the spells explanation:
Explosive Arrow (Avada Kedavra)
Deals a huge amount of damage by explosion where spells land. (acts like TNT except you could shoot it)
Fire Arrow (Incendio)
Places a fire where the spells land. (acts like Fire Chargers)
Ice Arrow (Glacius)
Puts out fire and turn water into ice. (Useful for when you don't want to cross over water)
Egg Arrow (Avifors)
Turns any mobs or animals into chickens. (In case of trouble, you just turn any mob into a friendly chicken.)
Lightning Arrow (Crucio)
Strikes down a lightning on anything and tortures it. (Use it on a pig and see what happens)
Anyways thats pretty much it for the mod-texture pack.
