I will buy the pony and name it Lydia! Below is a picture of the little cutie. I will also buy some more gear to load up my cart. Whether it be in the mining town or back home. I'll get some:
Adventuring Gear; 5 uses, 20 coins, 1 weight -- x1
Bandages; 3 uses, slow, 5 coins, 0 weight -- x2
Poultices and Herbs; 2 uses, slow, 10 coins, 1 weight -- x1
Healing Potion; 50 coins, 0 weight -- x1
Antitoxin; 10 coins, 0 weight -- x3
Dungeon Rations; Ration, 5 uses, 3 coins, 1 weight -- x4
Bag of Books; 5 uses, 10 coins, 2 weight -- x1
Throwing Dagger; thrown, near, 1 coin, 0 weight -- x10
Shield; +1 armor, 15 coins, 2 weight -- x1
Pony and Cart; 50 coins, load 20
Total Cost = 217
Total added Weight = 10
I will have 104 coins remaining after purchases.
For leveling up, I'll boost Spriggy's intelligence and choose the new move Multiclass Dabbler to learn to cast wizard spells. (I'll increase the weight of my songbook to 1 so that it can double as my spellbook.) I will choose Charm Person, Invisibility, and Magic Missile as Spriggy's starting spells.
