The Deadly Simplicity Cleric class feat increases your character's damage die with their deity's favored weapon by 1 size (or increases it to d6 if the weapon is an unarmed attack and it's lower than d6).
A monk has a d6 fist, due to powerful fist, so getting the Deadly Simplicity class feat whilst worshiping Irori, would increase the die to d8.
Does that go for Style attacks, as well, though? Or are they considered different weapons from the Fist weapon? Or are they not even considered weapons at all?
Would it make, for example, Dragon Style's attack from a d10 to a d12? Or would it remain d10?
Thinking on how could Multiclassing be implemented in 2E, using the current character progression as the main skeleton, I came up with the following idea:

Things to note:
-Class Features = Class Feats
-Each level up, you choose 1 Class. You gain one level on said class(and its hp).
-You can have levels on multiple classes.
-You can then gain Class Feats, provided you meet their Class Level requirement.
-Some Class Features are Level 0 (Cantrips, for example), meaning that you can take them without any Levels on said Classes, even at character creation (Lvl 1).
-At Level 1, you have 10 Proficiencies that you can choose to spend on Preception, Saves, Weapons, Armor, or Spells.
-At 4th level, and every two levels thereafter (6th, 8th, 10th, etc), you can gain 1 more Proficiency, or increase one proficiency you have by 1 level. Maximum: Expert. At 10th Level, Maximum: Master. At 16th Level: Maximum: Legendary.
