Plantera

Main article: Bosses

Plantera is summoned by destroying a Plantera’s Bulb, which is found in the Underground Jungle after defeating all three Mechanical Bosses. It has 30,000 HP (42,000 in Expert Mode.) Also, if you exit the Jungle with Plantera following you, it will turn into Enraged Plantera, which multiplies all of its stats by 3.

Plantera has two stages. In its first stage it clings to solid blocks using vine-like hooks and fires Seeds (and eventually Poison Seeds), which are much like Spiky Balls. In its second stage Plantera has increased speed and charges at the player. It will also release tendrils from its main body. In Expert Mode, the tendrils are attached to each hook instead (3 on each), adding approximately 9 tendrils.

Once Plantera is defeated, the Dungeon will automatically spawn more difficult Hardmode enemies, such as the Paladin, and more varieties of loot can be dropped.
