Somatic Hypermutation

Changes DNA, cores, shops, drops, or rerolls; its value commonly compounds over a longer run.

Remains active after acquisition; no extra input is required once its stated condition applies.

Mutations are not slotted organelles; unless the text limits a target, read the effect as applying to the whole character.

It can be acquired repeatedly; whether scaling is additive, multiplicative, or trigger-based still follows the effect text.

It is not classified as a typical downside mutation, but it should still match your damage source and resource plan.

Selection weight is relative likelihood in offer pools; reward drop rate is a separate reward-source parameter, not a power score.
