Solo guides?

/dev makes for a very methodical and slow soloer. While it is quite safe, it's a very different feel than soloing a /em, /ice or really any other secondary. You can easily solo just as well by taking a primary that offers a lot of active mitigation (like ice or energy) and taking a solid damaging secondary to help with the more difficult enemies.

With some range and AoE defense you can blast safely from range without harm but without forms of mitigation to keep enemies at range that would be useless. The ST immo is good for one enemy but not for groups.

I have only really taken 4 blasters to 50 2 different primaries though.

I will say this Fire/Fire without some form of defense/IOing is going to be rough, but that was with the old defience and just old haven't really touched him since he hit 50 in like i5 or i6

My next project was Fire/Dev, this was much better I don't feel /Dev slowed me down, it actually felt pretty fast and safe. Targeting Drone makes for a great passive to hit buff, you won't miss much. Cloaking Device helped get to the Range/AoE soft cap slightly easier. Caltrops + RoF combo is sweet. With softcapped range and AoE this guy was pretty deadly from range on test he can solo up to + 5 people without much trouble. I also have some good recharge on him too and he kinda spam Breath and Fire Ball after dropping the Caltrop combo.

Rad/Fire this is not a live combo yet but I had to try it out and I will say this at level 39 if you are slotted correctly you will be AoE death. With Fire Aura and Hot Feet running, do irradiate, Neutron Bomb, Combution and FSC this can effectively take out up to LTs and put a dent in bosses.

Rad/Energy/Elec this also is not a live combo but this is a deadly combo as well good job at range, Boost Range helps this combo out a lot as does Powerboost. With Powerboost near perma I usually hit that before I go into a fight and start of with Stun and Cosmic Burst on two targets or the Boss. Boost Range helps get more effectiveness out of Static Charge and Electron Haze. Power Boost also boost the defense of Maneuvers and Weave.

Those are just some tips with those sets, but honestly as a blaster there are three ways of survival on soloing with a blaster.

1.) Kill before being killed, you can use IOs to build up damage and recharge so that you can pretty much kill a target before they get a chance to do some good damage on you. Me personally this has not been an effective method, as Blasters already have low hp and close to no defenses is doesn't take much to get down to low health.

2.) Use mitigation and other active defenses, this way you are pretty much playing like a Dominator if you are familiar with CoV, you pretty much use mezzes and mitigation so that the enemy does not get that much of a chance to hurt you. This is an effective method, very effective with Ice and Elec, Ice you can slow them so that by the time they get another chance to attack they are dead. Elec = Sappers I have seen some good elec blaster and defenders keep mobs drained.

3.) Last but not least, my favorite, using IOs to build for defense it is easy to get softcap S/L with Ice mastery and Kinetic Crashes, but you can get positionals softcapped with IOs easily.
