Shell Effects
When you apply a Shell to a weapon or armour, it rolls a set of random effects. This page lists every effect that can appear, together with the value range (min–max) it can roll for each option tier.
How to read the tables
Each effect rolls at an option tier:
C → B → A → S
The higher the tier, the rarer the effect and the stronger its value. The columns show the min–max value the effect can have at each tier; a dash (—) means the effect cannot appear at that tier.
The same effect can have a completely different power depending on its tier — always check the tier badge, not just the effect name. An S effect is always the best roll.
