Permanent upgrades, purchased from Armor Ace at the Surface Camp, are the most impactful way to strengthen Shovel Knight over multiple runs. These upgrades persist even after you fail a run, making each attempt contribute to your overall progression. Key permanent upgrades include increasing your maximum Health, expanding your Magic Meter, and unlocking additional Relic Slots. Prioritizing these upgrades early on is highly recommended, as they provide a consistent power boost that makes subsequent runs significantly easier. More health means more room for error, a larger magic meter allows for more frequent Relic use, and extra Relic slots enable more diverse and powerful combinations. While these upgrades can be expensive, the investment is always worthwhile. Focus on acquiring them whenever you have sufficient Gold. The cumulative effect of these permanent improvements will eventually allow you to overcome even the toughest challenges the Dig has to offer, turning seemingly impossible runs into achievable victories.
