Proficiency Scaling

You can no longer gain proficiency in all armour or weapon types at once. Weapon and armour proficiencies are now "tiered". They go as such: Weapons: simple -> martial Armour: Light -> medium + shields -> heavy   There is no way to go up more than one tier. For example, if you only have light armour proficiency, you can get medium armour and shield proficiencies, but not heavy armour. This applies mostly to muliclassing, and also feats.   For example, a wizard who takes a level in fighter has no armour proficiencies. Therefore, when they multiclass they only gain light armour proficiency. Only then could they advance to medium armour and shields, and so on.
