Terraria is a game you must learn as you play, making it difficult to determine what equipment works best for different classes. The Summoner archetype specializes in conjuring Minions to take damage for them, making them great at farming enemies and multitasking. Recent updates have changed some of their best tools, making it harder to determine their best gear as a primary or hybrid class.
