Mutant Tarantula

The Mutant Tarantula is a Minibosses which spawns very rarely when a player doing the Tarantula Broodfather quest kills a spider.

Spawning
Mutant Tarantulas spawn rarely during Tarantula Broodfather quests when the player kills a Spider-type mob. When this happens, an explosion effect takes place and the Mutant Tarantula spawns.

Behavior
The Mutant Tarantula has. It seeks out and attacks the nearest player, preferring the player who spawned it.

It moves more slowly than its cousin the Tarantula Beast. However, it is far more deadly, dealing 5,000 damage per hit - enough to kill players wearing maxed out Tarantula Armor within 5 hits.

Tips

 * Beware of it when it spawns, it does ludicrous amounts of damage (5000) even with Tarantula Armor so be careful and hit it from afar with a Scorpion Foil. If you don't have a Scorpion Foil, run, because even if you have 10k kills on every piece of your Tarantula Armor it can kill you in 4-5 hits (may kill in less hits if you don't have Tarantula Armor).
 * An alternative strategy to beating this miniboss is to gain the lower ground against it; standing on a ledge 2 blocks beneath the miniboss, it will generally land no hits against you, and with virtually any decent late game sword, such as an Thick Scorpion Foil, one can take down a Mutant Tarantula.
 * A strategy that some use is fall damage. Knock the miniboss of a high ledge, and it will take high amounts of fall damage as fall damage is a percentage of health. After knocking it off, jump down to deal the death blow(s).
 * Another strategy is to lure the miniboss to a place far enough for the AI of the miniboss to stop working. This will make the miniboss not be aggravated and one can easily kill it down with no risk.
