I can't speak for all combinations, but in the early days of my Ice/cold corruptor, putting frostworks on my teammate Dark Armor Brute made a big big difference.

William Valence, you don't give O2 boost enough credit. It also has endurance drain protection, breaks stuns (aka wakies, too) and sleeps. It has really good range for a single target buff, +perception is a good thing, not a cost.

TL;DR thread: one choice only supplants all: FREEM!!!

I cant follow this thread, when did doms and trollers get energy primary?

Lady Mage, her defender kinetic spouse, SG shield tank and my coalition cold defender walked into an alpha unlock Ramiel arc. Sadly, there were few Rikti survivors and old Trapdoor and Minotaur were mere speed bumps. I suggest something in the spiritual alpha tree LM: heal, recharge and stun (scrambled thoughts with more duration, mmmm).

Not sure if you are familiar with the alignment tips/merits. It's a great way to earn the A-merits for the unobtainables. Also, don't forget 50s get a roll for content when exemp down, so even lowbie TFs with maximum spawn counts can be tasty for alpha components/shards.

First, I suggest you need two builds, team and solo. Decide if you want SOs, generic IOs, or sets for either or both. For sonic as well as forcefields and cold having team buffs is unnecesarry in solo build. If it were me, I would generic IO the solo and set build the team build.

I plan to go 3 slots: 2 full IOs of def/res, and the third is either def/rech or /end (res/rech or /end) except as folks noted for my forcefield defenders that six slot for red fortunes.

I may never do a i-trial

It's only one phase, but I don't like using psy damage at low levels on skyraider jumpbots, council/5th mechmen, (or Rikti drones). The only thing I would avoid on Elec/? doms would be a secondary power with a long DoT like combustion, but fire works, too.

I lean to Spiritual on my /darks. More recharge, more dark regeneration, or other end replenish power.

Just my two influence about the Banished Pantheon in Dark Astoria for the Numina TF, I was milling about slaying the undead on my squishy when I was confronted by a BP ambush that conned at level 40. Now, THAT was a surprise!

We need more forcefielders in Galaxy City, stat!!!

It's a great day to be a buffing style mastermind. That is all.

Flashfire, Cinders, Char all holding boss class spawns with one application is really good mitigation. The recharge bonus you need to get perma-dom really pushes the availability of your stuns and holds, too.

Poor fire... no confuse powers.

-Def still has a place against +4 and AVs.

I like my Demon Summoning/thermal guy as well. Overall, I would say this is a successful build. There are minor tweaks/discussions. I see you frankenslotted your Summon Demons and Summon Demon Prince. I certainly approve. I didn't go with any hold enhancments in my Demon Prince; I can't fault you for putting some accuracy in the hold. You might want to consider that the Demon Prince has a lot of slow powers that do not do damage and so he might suck down more endurance than you would like.

IMHO forge is underslotted. Forge as well as Hell on Earth help make up for slotting choices to cover endurance usage. I chuckled some when I saw a six-slotted Power of the Phoenix; you must run on some really tough PuG teams As of Tuesday, you will have less concern for endurance reduction in the shields. You do have some nice bonuses in your resistance slotting.

I use group fly on many of my masterminds. The chief reason I take it is to overcome the bad pathing that pets utilize to follow me between levels in maps. I really don't like to fight going up the switch back ramps and such.

Group fly also works great when fighting knives of artemis with the caltrops that ALSO have a fear component.
