Do not upgrade every set evenly. Tears of the Kingdom rewards purpose-based upgrades: your common defensive set, environmental resistance gear, movement gear, and combat-focused sets should come before collection-only outfits.

Collection advice
Ore
Caves, Depths, and volcanic routes support upgrades and rupees
Monster parts
Do not sell everything; keep common upgrade materials

Gather by environment, then target-farm missing pieces
Dragon materials
Farm once you know what you need
Rupees
Mix ore, meals, and quest rewards instead of selling rare parts blindly
Beginner Rhythm
Start with baseline defense and environmental resistance.
Before Rito, desert, or Eldin routes, check cold, heat, and flame needs.
Midgame, improve travel gear for map and shrine cleanup.
Before late bosses, focus combat and survivability sets.
Leave collection-only sets for post-story cleanup.
