The DLC includes five new witch classes, a summoning spell, a side quest, and more. Visit the new Steam page to learn about all the new stuff. Below, I discuss one new addition in detail -- zero-cost spells!
PREVIEW: ZERO-COST SPELLS
These two spells cost neither SP nor HP to use.* Both offer SP recovery -- especially useful to witches who don't have a lot of consumables -- and one even heals the young witch.
*Well, sort of. See below!
CHALICE OF NIGHT

This is a versatile spell that restores 2 SP and buffs your Wisdom by 3. This makes reaping SP from elf candles more efficient. It's also the only spell that removes the pesky Shaken status effect! It will do 2 cold damage to the caster, though, so witches with cold resistance are slightly better positioned to take it.
FLUSH OF YOUTH

The caster of this spell recovers 1-6 HP and 1-6 SP. This can be a great help in a pinch, and if you roll high, it can turn the tide of a battle. That said, there's also some risk along with the randomness: the caster gets -4 Will and a reduction in normal and acid resistances for three rounds. It is, after all, a spell about living in the moment.
