Goblin Summoner

The Goblin Summoner is an enemy that can spawn when a Goblin Invasion occurs during Hardmode. She summons Shadowflame Apparitions to attack the player. She can be considered a mini-boss, since she drops significant weapon upgrades at the beginning of Hardmode and involves a lengthy fight with multiple attack patterns. She has a chance to drop weapons which are themed after Shadowflame, all of which accordingly inflict the Shadowflame debuff.

Because of her high stats and relatively high difficulty compared to other goblins, she will present a challenge for new players.

Tips

 * She can be easily defeated with a ranged weapon (a rapid-fire ranged weapon may be recommended, as they have enough knockback to freeze her in place), a long platform suspended in the air, and Hermes Boots (or a Unicorn Mount/Minecart Track). Simply run away from the summoner continuously – if she is constantly moving she will not summon the Shadowflame Apparitions.

Trivia

 * Although the Goblin Summoner drops various Shadowflame weapons, she will never use any of them in battle. Even the Shadowflame Hex Doll, which is clearly part of her sprite, is never used.
 * Despite being named "Goblin Summoner", she does not drop any summoning weapons, though this name likely references her ability to summon Shadowflame Apparitions.
 * The Goblin Summoner is the only Hardmode-exclusive Goblin.
 * Despite its name, the Hemogoblin Shark is not a Goblin.
 * If one slows down the death sound of the Goblin Summoner, then they will be left with an audio that sounds like she screams "Help Me!".
