DS/Therm Build -- What sets?

So this is my first mastermind since sets came out (I know, I've been mostly playing Hero side). I'm kinda wondering what kind of set bonuses and stuff to aim for on this toon. Most of my other characters, I tend to stack +rech, but I don't know that +rech is all that useful for an MM. I want my pets to be all they can be .

So anyway, heres my stab at a build, with some slots. Therm I'll probably stick some doctored wounds into the heals.

This character is currently level 17. Its a leveling build, focused on solo PVE and maybe some group play once I switch him to hero side.

I haven't figured out what to do with my last 3 powers yet, if I want Anc/Epic or some other pool. I might swap out Hover/fly for Assault/Tactics earlier, but not sure . I have plenty of slots to throw around atm as well.

Thanks in advance .

Set Bonus Totals:

My Demons/thermal went hero and took the Cold Mastery. I like the AoE sleep its a good way to 'filter out' too large of spawns. There is some bug with power selection order, so you might want to check out which powers you want before going that route.

+Recharge is still quite beneficial for /Thermal, especially at the higher levels.

Be sure to throw the +Resist and +Defense pet uniques into Hell on Earth - Those help a lot in keeping your pets alive... at least as long as you stick near them.

Go for a +Defense shield (Frozen Armor or Scorpion Shield.) I found that it wasn't difficult to build in around 30% (or more) smashing/lethal defense (Scorpion Shield will also allow for an equal amount of Energy Defense...) Between that and Bodyguard with your Resist-heavy pets, you should be quite tough. (Between all the various +Resists, all your pets should be sitting around 75% Smashing/Lethal resistance, with varying degrees for the remainder.)

Speaking of which...

If you do this, take Crack Whip and/or Provoke. You want the enemies focused on you, not your pets.

I highly recommend crack the whip for grabbing aggro, taking the alpha shot in bodyguard, plus the extra -resistance.

Oh yes, I forgot...

You need to remember to pet End reducers into your Tier 2 and 3 pets! With their auras, they will be burning through endurance like mad.

I don't really think its worth slotting up any of the secondary effects the demons bring with them (Heals & Resist for the Ember Demon, Sleep, Hold, and Slow for the Prince.) So a full set of Blood Mandate is probably a good idea for these.

I am a lunatic, but I took two mastermind pet enhancements and four Pacing of the Turtles in my Demon Prince. That slow set has some accuracy, some damage, some slow, some end reduction, and the set bonus for accuracy isn't shabby. I felt that big slow aura on the Prince would make a big effect, along with all the cold attacks that have slow secondary effects as well.

So basically, I should focus my set bonuses around a bit of recharge, and whatever defenses I can get .

Sounds cool!

Thanks!
