Really like the combat and spellcasting material here. Have a creature-prep question for you:
Given the guidelines you mention for NPC creation and the considerations you offer for what sort of combat abilities different npcs might have, if we have (say) an orc who can block, how many times (or how much fatigue) would you imagine giving a monster like that access to in combat against the PCs? A certain number, and the players can wear them out? Or functionally-infinite fatigue, and the PCs then need to change-up their tactics? I can imagine both being viable, but I wonder from your own play what you found to feel good at your table.
Thanks for your time, and for your great work!
