(Pehkui required)
Sizey Changey id a mod that allows to use Pehkui mod into survival mode by adding Shrinking and Growing Potions but also some powerful armors.
Use JEI for recipies.
Sizey Changey adds potions and armors in order to change size. To brew the potions, you need to craft pills, there are four pills and each one determines the effect of their respective potion.
To brew a shrinking potion, you need a shrinking pill (check crafting recipe using JEI)
This pill can be used to craft a more powerful one, the red shrinking pill which shrinks the player more if used in a brewing stand. The result is a super shrinking potion. The same goes for growth potion.
If you think that the shrinking potion has limitations, like duration, player's speed and the incapacity to jump blocks. You can craft the Extrimum armor set. A new armor material was added, the Extrimum X, more powerful than Netherite but also harder to get and craft (check crafting recipe using JEI). If the whole set was equipped, the player will have a permenant shrinking effect but also a huge jump boost and swiftness effect.
