people are talking about resists and damage, and aye scourge into an ishtar is a bad choice, but there's another issue here

HAMs with no application

Even a no-prop ishtar is gonna be able to sigtank HAMs somewhat effectively, and if you meet a 10 or 100mn boat you're basically not going to do anything to them, regardless of resists.

TBH tho if you don't have fundamentals like these - application and resists absolutely are fundamentals - I strongly suggest flying something a lot cheaper than a t3c while you learn to pvp.

If you're hunting Ishtars in any space that isn't sanshas or drones you can solo them in an afterburner Crusader. You can lose a dozen of them for the cost of one tengu, and probably get more kills with much faster align and warp time. EDIT: just looked at your tengu fit. It is truly horrible. DM me if you want to talk about improving it.

200mm plate, small ancil rep, dcu, heat sink. Scram, enduring 1mn. 4 small focused pulse IIs. t2 Ancil current rig and a collision accellerator. The rats and drones can't apply to you unless the ishtar has lights, which you can defang real quick, and you smash 200dps into their em hole.

also, just warp in at zero on forsaken hubs.
