I'm still working on the Forge Engine (while juggling various updates to Hero Kids).
At the moment I'm developing the monster stat blocks so that the GM has all of the information they require at hand. The trick has been to provide all of the monster's information in a compact and usable form. Ideally, I want to fit two monsters per page (in an digest sized printed book), or four monsters per double-page spread for a PDF.
The important aspect is to assist the GM in managing the energy pool and attacks of multiple monsters. This has led me to include an attack line that shows the monster or character's basic attack, which they make by just spending the energy cost of the weapon, as well as their strongest attack, where they spend the weapon's cost and then add as much energy as possible to maximize the attack.
So the elements of the stat block are:
• Type and Size
• Attributes (Strength, Agility, Stamina, Influence, Intelligence, Acuity)
• Energy Pool
• Physical and Mental Defenses
• Health and Move Distance
• Basic Attack and Maximum Attack
• Specialized Combat Skills
