Yes, there will be a pledge manager and you will be able to make changes to your pledge in there.
Yes, you can pledge $1 now and when the pledge manager opens, upgrade your pledge in there.
There are not stretch goals but there are "surprises" coming along the way.
The minis are 28mm scale.
We are looking into it layered hero sheets or overlays. If it works out, we'll post an update.
The game comes with 10 "Order themed" dice. At most, a hero will roll 7 dice on an attack. If you don't like sharing dice very much, you can get another pack of Order Dice, or a set of "Chaos themed" dice as an addon.
All the "design your own" pledge levels will combine to be a single product which is an add-on, and not included for free in any pledge level (other than the Lord pledge level itself).
