Not modelled here
  • THE EXPLOSION IS THE WHOLE WEAPON AND ITS RADIUS IS NOT MODELLED. The mine deals no contact damage at all — both of the module's attacks are the same blast resolved at two different moments (mid-flight, or after it has stuck) — so this entry carries that blast as the shot's own damage and no `radial:` beside it. Against ONE target, which is what this arena and the board's rulers fight, the number is exactly right; against a crowd it is a FLOOR, because nothing within the published radius takes anything here
  • the mines are DETONATED BY HAND via Alternate Fire and several can be laid before firing them together (wiki). This sim detonates each one the moment it lands, which is the ceiling for a single mine and misses the play pattern the weapon exists for
  • mines STICK to surfaces, enemies and allies, and multishot throws them in 'a very wide horizontal spread' (wiki) — so on this weapon multishot covers ground rather than stacking damage on one target, which is the opposite of what it does everywhere else
  • the embedded detonation also forces a RAGDOLL, which is not a damage type and is not applied here
  • 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.

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

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.
