True, but it's a slow trudge:
8 Twin-Linked will generate 6 hits, for 12:12 --(GEG)-->9:6 --(CBD)--> 6:6.
SAP generates 3 hits, for 6:6 --(GEG)-->3:3 --(CBD)--> 2:2.
Net 8:8; it'll take a while, but it may go down. How many Vorchan can you kill by then? Good question. Centauri are a very hard march for the Drakh; Twin-Link DD is a great weapon against the Drakh.
