From the publisher blurb:
The Ultimate Adversary Resource for Genesys RPG Gamemasters!
Attention GMs! It’s time to stop rummaging through rulebooks and monster manuals, searching for that perfect stat block of the next adversary in combat! A GM’s life is arduous enough! Instead, this supplement only requires the GM to have an idea – a core concept – one that they can evocatively narrate and bring to life during combat proper.
This supplement presents a radical new method for Genesys RPG gamemasters to quickly prepare and run adversaries during Genesys combat encounters, while focusing on narrative freedom and flow of battle. The GM is no longer constrained to specific values and abilities of a small stat block, but instead can imagine any action possible and immediately determine its results. The system of Adversary Actions that is presented in this supplement gives the GM the freedom and flexibility to be tactical, reactive and engaging in any combat situation.
Foes on the Fly aims to achieve two main goals:
Save gamemasters a significant amount of time by allowing them to generate interesting, consistent and balanced adversaries literally on-the-fly.
Allow the GMs to imagine any kind of action an adversary could take during battle, and let them immediately determine that action’s results.
Foes on the Fly Narrative Adversary Philosophy
Besides having a vision for the adversary before combat begins, the GM should approach each combat turn with a story in mind. The descriptions of the five Adversary Actions (Attack, Guard, Hinder, Heal and Summon) are broad enough to mechanically represent any task an adversary would want to accomplish during combat, using whatever faculties they could narratively and plausibly have. The same action can be used to represent a multitude of different activities, and along with the Boost/Setback Dice Pool and the Proficiency Dice Pool, the GM can narrate any unique ability, powerful gear or special training the adversary might have.
