Proficiency

The Proficiency system is how the game determines whether to add a creature's Proficiency Bonus to a Die Roll. One can have Proficiency in Weapons, Spellcasting, Saving Throws, and Skills.

Weapon Proficiency

A creature can be proficient in entire categories of Weapons (Martial, Simple, Improvised), or it can be proficient in specific types of weapons such as Longswords, Longbows, etc. These proficiencies can be granted by the creature's Race, Class, or Feats chosen when leveling up. Having proficiency in the weapon one is using means that the Proficiency Bonus will be added to the Attack Roll. When the weapon is equipped in the main hand, it also enables special properties and actions of that weapon type, such as Tenacity, Piercing Strike, Flourish, Lacerate, Pommel Strike, and so on.

Spellcasting Proficiency

All creatures capable of spellcasting on the regular (i.e., without the use of magical items or scrolls) have proficiency in spellcasting. This means that the creature's Proficiency Bonus will be added to the Attack Rolls of spells, and to the Difficulty Class of Saving Throws imposed on others via spells. Although all spellcasters have it, the lack of spellcasting proficiency can nevertheless become apparent, when a creature not regularly capable of casting spells does so through the use of a magical item or scroll.

Saving Throw Proficiency

Having proficiency in a type of Saving Throw such as Strength Save, Dexterity Save, and so on, means that the creature making the save can add its Proficiency Bonus to the result. Each Class provides proficiency in two types of saving throw.

Saving Throw Proficiencies by Class

Druid	Fighter	Monk
Intelligence Wisdom	Strength Constitution	Strength Dexterity
Paladin	Ranger	Rogue

Skill Proficiency

Being proficient in a Skill means that a creature adds its Proficiency Bonus when making a corresponding Skill Check. Skill proficiency can be granted by a creature's Background or Class.
