I want to create a trigger that allows agility to influence dodge as a factor. Since there's no existing field for dodge within the constants, I’ll need to set up a trigger. My initial idea is to add a passive dodge skill to all heroes and somehow make the icon hidden. Then, I would create a trigger to set the dodge rate of this skill equal to each hero's agility stat. However, I’m not sure about the best event to use—should it be a periodic event, or is there a better approach?
