The Succubus is one of the most feared frigates ever to harrow the spacelanes and asteroid belts of civilized space, and with good reason: tales abound of its superiority over ships twice or three times its size. Whether you believe this to be fact or rumor, the Succubus will still strike fear in your heart.
The succubus is probably the least surprising of the pirate frigates (at least in the sense that it doesn't receive a unique bonus or have any aspect in which it's particularly unusual), other than of course its combination of weapon system and tank. As an amarr-caldari hybrid, the succubus is both a shield tanker and a laser boat. The other interesting aspect of the sansha line is their tendency to have plenty of spare high slots (and no launcher hardpoints), making them useful both for PvE and for cap warfare.
In terms of comparison, the succubus most closely resembles the harpy. With a 4/4/2 slot layout and 2 turrets (receiving both a fixed 100% damage bonus and a 5% per level bonus too) the succubus puts out fairly nice dps at respectable ranges. A shield tank is the obvious choice, and due to the cap consumption of its weapon system a buffer tank is generally preferable to an active one (although if fitting nos, an active tank can be an effective choice too). The two spare high slots give the succubus excellent cap warfare abilities, either supporting its own cap usage (useful as tackle in a gang where neuts are present) or to kill off active tanks on its opponent. My ex-girlfriend is still in my phone as Succubus because I think she is one. I hate her, so I also hate this ship and I made a terrible fit called 'Ashley'. Screw you Ashley. I want my sweater back.
The succubus receives a tracking bonus, and with an optimal range on pulses of about 10km with scorch, there isn't really a range at which it can't hit effectively (other than, obviously, outside of web range). The succubus has tank and gang on par with an assault frigate but not superseding them, and an equally tanky/ganky ship should have a reasonably chance of beating it. As with the other shield tankers mentioned above, em and thermal (if anti-em rigged) are the best damage types to employ against it.
