01

How it works

Upgrade resources used in weapon progression. Equipment should be assessed in the actual inventory; Volpedia does not invent damage tables or drop rates.

02

Practical strategy

Spend them on a weapon whose passive and scaling you plan to use for multiple regions.

03

Mistakes to avoid

Upgrading every new drop equally spreads materials too thin during the early acts.
