So,
I've just defeated the Green Hag. In her Lab you can find several potions. Here I will list what they do incase anybody was wondering.
- Potions
Lover's Avarice - Reduces Wisdom by 1 until next full rest
Mother's Loathing - Gain Bite [2d4] for 50 turns or until next long rest
Missing Pets - 3 Turns, Lowers advantage on ability checks and attack rolls
Wilted Dreams - 50 Turns, Watched from the shadows, taking upon rest (?)
Insanity's Kiss - 4 Turns, Hostile to all (Beware)
Stillborn - 4 Turns, Bleeding from the inside. 1d6 piercing at the end of each turn
Lost Time - 50 Turns, AC reduced by 2. Can't take reactions
Broken Promise - 50 Turn, Increases Strength by 2 until next long rest. Afterwards Strength is indefinitely reduced by 1
Heart of Stone - Resistance to poison until next rest
Faltering Will - Disadvantage on Wisdom saving throws until next rest
Enjoy and good luck on the fight. There are some more interesting items which I won't spoiler here.
