Movement
From Wildermyth Wiki
Tactical
A hero's movement on the battle map is determined by their speed.
Humans start with a base speed, modified +1.7 by each of their natural legs they still have. It is also modified by age.
Campaign
Speed also affects movement on the overland map.
Groups that start together and are moving to the same destination or task will stay together, moving at the speed of the slowest member.
