Adjust Initiative based on planned movement

[WisdomOfWombats]

Move affects the initiative rankl according to page 125: "If your character is unengaged, they can move around 30 meters in a combat turn if they perform no actions other than to defend themselves (parry or dodge). Moving between 6–15 meters means that your character acts at 1/2 their normal DEX rank. Moving between 16–29 meters in a combat round means that your character acts at 1/4 their normal DEX rank. These modified DEX ranks are cumulative with penalties for additional actions, with movement modifiers to DEX rank being applied first."

I know this moves into fiddly territory. Maybe take a look at "Against the Darkmaster" system for Foundry. That system also phased initiative.
