Does anyone know were to get this blaster pistol?
Hylo Visz's Sidearm
It's an Armstech craftable, just ask around. Needs three biometric crystal alloys (you know, the mat from end bosses in HM flashpoints) so have those prepared.
On topic, I use this baby on my sawbones, looks a lot like some kind of old-school .357 magnum revolver. Farmed Athiss end boss several times at level 50 just to get it.
Works well with a scrapper too, I imagine, looks heavy enough for all those pistol whips.
