  • the grenades are DETONATED BY HAND — 'it launches ballistic grenades that can be manually detonated with Alternate Fire', with no arming delay at all (wiki). This sim has no second trigger, so every grenade goes off the instant it lands, which is what a player detonating immediately gets and is therefore the ceiling. What is lost is the play pattern the weapon exists for: laying grenades and firing them together
  • only five grenades may be live at once, and multishot counts towards that limit (wiki) — so on this weapon a multishot mod buys fewer shots rather than more damage per shot, which is the one place multishot is not simply good. This sim resolves each shot on its own and never hits the cap
  • 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

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.
