A Cobblemon addon mod that makes your Pokemon grants buff effects, with a progression system

Cobblemon Buffs allow you to benefit from your pokemon's type & level/friendship by bringing "Buffs"
Buffs are effects from vanilla Minecraft, the power of Buffs lie in the "Tier" your Pokemon is, there is 3 tiers: Tier 1, Tier 2 & Tier 3, and ranking up Pokemon's tier depends on its "Power" which is a combination of the Pokemon's level and friendship
Each type grants a unique Buff (e.g fire type grants fire resistance temporarily) each Pokemon in your party that has a unique type gives the Buffs
First, when there is a new Aura (Auras are types) via new pokemon/type you will be notified

When you level up a tier, you will also be notified

To view progress & the Buff gui, to do this, press what ever keybind it is to open chat, when you open it, the same panel from the notifications will show up (above the party HUD)

then press the panel, this will bring up the Buff gui which includes your power progression, your party to go through and the Tier of the pokemon
with this gui, you can press the "?" button to check what a type provides

As a warning, this mod is in Beta, expect some bugs (although most surface ones are covered), right now it's in a pretty good state, although expect alot of updates, some buffs might be better than others, i plan to balance things out, but want the communities opinion first
