Not curated. The effect text above comes straight from the game export, which carries per-mod errors. The builder refuses to compute with it.
Drain by rank
- R0 2
- R1 3
- R2 4
- R3 5
- R4 6
- R5 7
A matching polarity halves the drain, rounded up; a mismatched one costs more than no polarity at all.
