Combat without a stamina bar
The official description gives three reliable anchors: unrestricted stamina, posture breaks and tactical melee/ranged upgrades. Use them to structure practice.
Practice the three anchors
Use the freedom
No stamina restriction is listed in the official combat description. That changes the question from “can I afford one more swing?” to “what is the enemy’s next commitment?”
Break posture
Posture breaking is an explicit part of the store description. Observe which attacks create an opening, but do not write exact thresholds until tested in game.
Switch tactics
Both melee and ranged weapon upgrades are mentioned. Record which option solves the current encounter instead of assuming one universal loadout.
What is still missing
A publishable advanced guide needs verified weapon names, enemy patterns, upgrade costs and version notes. Those are deliberately not invented in this first site version.
