  • the projectile explodes 'on impact OR travelling 15 metres' (wiki), so past 15 m it goes off in mid-air and the direct hit never lands. This entry carries the 15 m as a reach, which stops the direct hit correctly and stops the EXPLOSION with it — so a shot fired past 15 m is worth nothing here where in game it would still blast whatever it went off beside
  • 'Projectiles guarantee knockback against enemies; most are ragdolled and launched' (wiki), and the module gives the impact a forced Ragdoll proc. A ragdoll is not a damage type and this engine's proc list holds only damage types, so it is not applied — which is the whole reason a player carries this weapon
  • 'Projectiles reflect off of solid objects and surfaces' (wiki) — this arena has no walls to bounce off
  • the blast needs no line of sight and goes through walls — this arena has no geometry, so nothing is ever behind cover and the perk pays nothing extra

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.

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.

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.
