Wizard is one of the classes impacted most by Renewal mechanics for players who are used to Classic 99dex, to obtainb 150dex instant cast. Even traditional renewal cast formulas have been customized for RE:Start putting them in a weird middle ground. Int will increase casting speed dramatically and instant cast in unobtainable even with maxed int/dex. Currently, casting reduction based on stats is 1dex = 2int. So 10dex will reduce casting time the same amount as 20int. Meaning a wizard with 120int and no dex will have the same cast time reduction as a wizard with 60dex and no int.
