Cytoserocin Site (nullsec sov)

Booster gas · cyto · defendedNull Security

The big cytoserocin sites — 18,000 units — spawn only in deep nullsec sov regions (Catch, Delve, Vale of the Silent, Tenal, Fountain, Cloud Ring, Wicked Creek, Feythabolis). Unlike their lowsec cousins these are deadspace pockets with cloud damage (up to ~1,000+/cycle by flavour) and NPC defenders.
