Shovel Knight: Treasure Trove

There are 2 "Towns" in the game, the Village and the Armor Outpost. The Village is where you can purchase Health and Magic Upgrades, as well as Relics. In the event you miss a Relic in a stage, (Found inside a large Blue Chest with the NPC "Chester" inside it, who will sell the Relic to you), you can return to the Village and talk to Chester, who will then have the Relic available for purchase. However, if you miss the Relic in the stage and want to buy it in the Village, Chester charges you more Gold for it. (If you want to save some money, you are able to go back to the stage where you would find the Relic and, if you find it there, Chester will still sell it to you at the lower price.) The Armor Outpost is where you can purchase new Armor and Shovel Skills.

Health Upgrades:
Health Upgrades are acquired by giving a Meal Ticket to the Gastronomer in the Village, and eating the Meal he prepares for you. Each Meal increases your Health by 1 "Peg". Meal Tickets are found in 2 ways:
Three can be purchased from the Goatician for 1000, 4500, and 6000 Gold, respectively.
Upon defeating all Knights of the Order of No Quarter in a particular set, (first, 2 Knights, then 3 Knights, and finally 3 more Knights), Shovel Knight will have a Dream while he is resting at his Campfire. Upon the conclusion of the dream, there will be a Red Chest sitting beside the Campfire, (you can actually see it before the Dream starts). Inside will be a Meal Ticket. There is a total of 3 Tickets that are acquired this way.
After eating all 6 Meals from the Gastronomer, you will have 10 "Pegs" of Health, which is the Max.

Magic Upgrades:
Magic Upgrades are acquired by purchasing them from the Magicist once you have obtained a Relic that consumes Magic. Each upgrade increases your maximum Magic by 10.
They can be purchased for 1500, 2200, 2800, 3400, 4000, 6000, and 8000 Gold, respectively.
After purchasing all Magic upgrades from the Magicist, you will have 100 Magic, which is the Max.
