  • it 'reloads 50% faster from a fully depleted magazine' (wiki), and this engine carries ONE reload time per weapon. This sim holds the trigger until the magazine is dry, which is exactly the case that reload applies to — so the 3 s here is the SLOW reload for a fight that would always earn the fast one, and the weapon is understated
  • the explosion arrives 0.6 SECONDS after the bolt lands, which the page says lets an enemy walk out of it — this engine resolves the blast at the point of impact immediately, so nothing ever escapes one here
  • ON KILL THE BODY FOLLOWS THE BOLT, damaging anyone in its path and pinning the corpse to walls (wiki). It is a second damage source that only exists once something has died, and this engine has no ragdoll and no wall for it to pin against — so a bolt weapon fighting a crowd is understated by however much that corpse would have hit on the way past
  • 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
  • the blast staggers the WIELDER in game — this arena gives the player no body, so a build that would be unplayable in a corridor costs nothing here

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.
