Arctics Undertale Souls

The Determination Soul has gained the ability to LOAD their position after saving.

The Perseverance Soul has gained the ability to cancel out certain souls' effects.

You can now take DT from human soul jars by right-clicking them with an empty bottle. 

The new DT viles can be used to turn a monster into a Boss Monster.

Boss Monsters have 40 hearts, move slightly faster and are larger than a normal player. They can also use special magic, though not much is available at the time.

If not used properly, a monster can gain the falling-down effect, which will dust the monster when the effect is up.

When monsters dust, there is now a sound that plays.

There is a new stone type called ruined stone that will generate underground. With this new stone type, you can create ruined bricks and smooth ruined stone. These bricks are a reference to the ruins' brick walls.

A banner pattern has been added; this pattern is a reference to the DELTARUNE. The banner can be created using Monster Dust in a loom.

Burnt and Frosted Planks can be used to make boats.
