Vul'N'Res adds automated handling of Vulnerabilities and Resistances on saving throws, based on simple effects placed on actors in the Combat Tracker (like Magic Resistance):

   - Magic Vulnerability / MagVuln

   - Physical Vulnerability / PhyVuln

   - Physical Resistance / PhyRes

When a creature makes a saving throw, this extension automatically determines whether the save is magical or non‑magical and then applies:

   - Disadvantage on magical saves → Magic Vulnerability or MagVuln

   - Disadvantage on non‑magical saves → Physical Vulnerability or PhyVuln

   - Advantage on non‑magical saves → Physical Resistance or PhyRes

What it does

Simply apply an effect that contains the tag you want to achieve the desired result.
