World Spells Scrolls

hey guys, i see lots of people have been trying to get new classes, so then i thought what if there was new ways to get spells then i thought of more things like teleport scrolls, so basically there are scrolls that either use mana, health, soul points or Emeralds/Emerald Blocks some example spells below

FarmMix- turns you into a farm animal chicken/cow/pig/sheep for 5 seconds making mobs not attack you, sounds op, but doesnt let you talk to villagers, the msgs would be jibberish like cowfusion, if you buy this spell 25 times, upgrade 2 = turns you into the farm animal for 10 seconds, and upgrade 3 lets you be in animal form for 20 seconds.

Ice Walk- (basically like frost walker from 1.9) when you walk over water it turns into ice, making it easier to travel the ocean. upgrade 2, 1 block more around then frozen, upgrade 3, 1 more block so like 3x3.

Hercules's Strength- gives you strength 4 for 5 seconds, upgrade 2 - 6 seconds, upgrade 3, 7 seconds.

etc, these are only examples, but you cant buy the spells near any towns, and from the same merchant, for example farm mix is near cowfusion quest guy, they will usually not be around any towns, and will cost some EB to buy, for example 10-30eb

 

I think it's pretty op

 

they would have to be nerfed, obviously, i was just rushed so i couldnt think of any good ones, i had to finish my homework, plus there going to use up mana, health, soulpoints, or even more money in ur inventory.

 

Ok but it's seems like a fine idea but it's just really op
