Mana , Essence , PSI, and Intent bars
Several weapons, such as Donkey's Jawbone, with its own rage mechanic, Poison Wand, Slingshot, the Action Claws, and Samurai Yaiba Bongos.
Platinum: an upgrade to gold armor, giving it the durability (and mining power, but not speed) of iron.
Rubies: a more valuable gem, used in trading with villagers (currently only wandering trader) for more expensive or useful items.
Spider Ranching: renewable resources through the power of spiders and string, inspired by Forestry.
A handful of curios to aid you
Bundles, but better: A simple 9 slot backpack, and crafted with leather! Now it can actually be used in a way that DOESN'T make you want to smash your head against a wall.
A new structure, being a tiny house -- it holds new loot!
The Season of Harvest: the first seasonal event. Takes place from October 1st to November 30th. Currently only adds Halloween content, and only in the form of candy that can be obtained from killing mobs for candy baskets. You can activate the Season of Harvest outside of this time period using the Pearl of the Harvest.
PSI Technique Curio slot and PSI Technique keybind (default: Z,) along with the PSI Technique: Medamaude, which allows you to place a waypoint and teleport back to it at the cost of PSI.
Marble -- new decoration block. Polished Marble comes with the expected variants
Omega Charge -- TNT that explodes into a pile of more tnt, including TNT minecarts. The demolitionist's dream and the ender of friendships.
And more!
