  • THE RELOAD GRENADES, which are most of this weapon and the whole reason it is built: "Reload throws 3 grenades at a 45 degree angle towards the reticle that explodes in 3-5 meter radius on impact", and reloading FROM EMPTY makes them far larger — 658 Corrosive apiece in 5 metres at 31% crit and 59% status, against 74 in 3 metres at 11% and 43% on a partial reload. Three of the from-empty grenades is 1,974 damage, which dwarfs the beam that earned them. The engine has no hook that fires an attack ON A RELOAD, so none of it is counted and the number on screen is the beam alone
  • the reload-from-empty penalty that pays for them: an innate -20% Reload Speed, additive with Quickdraw, taking the 1.7 s reload to 2.125 s. Not applied, because what it buys is not either
  • this weapon will never reload on its own and must be reloaded manually — a habit cost this arena does not charge
  • Critical Mutation, the Catabolyst family's exclusive mod — a weapon-exclusive card outside the pools this roster loads

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

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.
