Third Caster

Third Caster is a slang-term that appears on /tg/ in reference to Dungeons & Dragons 5th Edition. A Third Caster is any class capable of spellcasting with the following traits:

• They start gaining access to spells at 3rd level.
• They are usually a spellcasting subclass to an otherwise non-spellcasting class.
• They can reach up to 4th level spells.
• When multiclassing, it takes 3 levels in this class to gain 1 caster level.

Third Casters in D&D 5e currently consist of the Eldritch Knight subclass for Fighters and the Arcane Trickster subclass for Rogues.
