Not modelled here
a MISSED shot drops the combo counter and this entry cannot miss — the only thing that misses here is SPREAD, and this one lands on the reticle, so nothing but its 2 s timer ever takes a stack off. A player who pulls the shot loses the combo and this sim never pulls one
the LOWER zoom levels are not modelled — this arena has no field of view to trade for magnification, so the scope always sits at its top level and its best buff

Stance
A stance decides what the weapon actually swings: it publishes a combo per mode, and installing one replaces the weapon's own. It also GRANTS capacity instead of costing it — 10 on a slot of its own polarity, 5 on a bare one, 4 on the wrong colour.
Exilus
A polarity can be swapped between this slot and a main one — the slot stays Exilus. So its polarity counts toward any build, even one that leaves it empty.

Sim
1 · The fight who you are shooting at, where, and for how long
2 · External bonuses what the wielder is doing, and what others hand them — a ticked number replaces the wielder's own
3 · Limits what this run is allowed to assume
4 · Buffs the stacks the run STARTS with — the fight still grants and decays them on their own triggers
5 · Extra stats anything this weapon is handed from outside its build — it lands in the same bucket a mod would
6 · Warframe buffs abilities cast on this weapon — set your Ability Strength and the values follow
7 · Measure what to read off the run — the scenario's own term, so an official ruler pins it
The whole fight — every field, including the ones this weapon hides

Aura
An aura hands capacity back instead of costing it: twice its drain on its own polarity, 80% of it rounded down on another. A polarity moves between all ten slots, the aura's included.

0 / 00 Forma
Nothing a companion seats moves a weapon's numbers yet: no robotic weapon reads its wielder's stats, and no precept is run. What this answers is capacity and Forma.
Operator
Only the active school's nodes apply. A node that needs an Operator action counts only when you say it is running.
