Notwithstanding the attractiveness of Soul Drain, if you go Power Mastery you get Power Build Up, which buffs Farsight and allows you to softcap defenses.

Unless you really need the set bonuses, don't recommend slotting Gravitational Anchor in Tenebrous Tentacles. The base immobilize duration is plenty long. I recommend slotting damage procs and possibly a range IO. Procs in Freezing Rain (or any rain power) are not recommended. Go with 2 recharge IOs or the defense debuff set of your choice. Not sure why you're skipping Hurricane. It's certainly situational, but it's one of the strongest tohit debuffs in the game and can be used to pin foes in corners. 5 slots in Combat Jumping is 4 too many. The defense it provides is very low and not really worth enhancing. You don't need the Stealth IO in Super Speed. Steamy Mist + Super Speed already makes you invisible to everything but snipers and drones. Switch Adjusted Targeting to Gaussian's in Tactics and include the Build Up proc.

I 3-slot Lifegiving Spores for endmod/endred.

Unai Kemen is a lvl 45-50 contact. He should be referred to you, but if not you may be able to just walk up to him. You can't not get him. Any missions he gives you will be at your level at the time. If you want lvl 50 missions, you need to be lvl 50 when you get them. You can pick up Unai as a contact at any time after lvl 45, just don't take any missions until lvl 50.

Storm Kick is 100% chance of knockdown and Dragoon's Tail is 75% chance of knockdown. Even if you don't want to blap, that's a lot of mitigation.

They can still be purchased from the Merit Vendor, albeit for 100 merits each.

I just took Dark/Dark to 50 and am really happy with the new Touch of Fear. I highly recommend proccing it out, however, only use Melee AoE or Taunt procs (the damage and taunt are AoE, but the fear and -tohit are single target). I think I have the Obliteration, Eradication, Scirocco's Dervish and Perfect Zinger procs plus one acc IO. At some point I may swap in an Armageddon.

I'd be happy if they just made the same changes to Black Hole that they made to Dimension Shift.

Nature has Entangling Aura and Radiation has Choking Cloud, both a 15-foot radius AoE toggle with an 80% chance for a mag 1 hold and 50% chance for a mag 2 hold (both auto-hit). If you enhance the hold duration, you can lock down everything in the radius pretty easily as long as you hit bosses with your ST hold. Radiation also has EM Pulse, a 60-foot radius PBAoE mag 3 hold with a 50% chance for an additional mag 1 hold (albeit on a 5 minute recharge).

You may want to refer to the extensive guides that @Redlynne wrote for SR/MA

This seems accurate. One thing to add, is that if the original target dies before the shade pets expire (60 sec), they will attack a new target. Not sure how that target is selected or if Haunted is applied to them.

Assault on a brute is 10.5% +dmg, barely noticeable alongside Fury (which typically provides about 200% +dmg). I would definitely skip. Build Up is 80% +dmg, with the Gaussian's proc adding another 80%. If you slot no recharge and just the proc, its virtually guaranteed to go off every time you use Build Up. Not essential, but worth taking if you've got a spare power pick that you don't want to spend slots on. I frequently take it at lvl 49. Hasten will make Build Up available more frequently without impacting the chance of the Gaussian's proc going off. Whether you need it for your attack chain or other powers depends on your primary/secondary and power selections.

Major props to @Oklahoman for his frequent and incredibly well organized Incarnate Trial badge runs (as well as his MSR runs).

I don't worry about capping defense with Dark Miasma. Between Darkest Night and Fearsome Stare I've got 50% -tohit, plus another 65% from Fluffy's Chill of the Night and Darkest Night.

Going from memory, I think I have 4x Cloud Senses and 2x Touch of the Nictus. Fluffy spams Twilight Grasp quite a bit and enhancing the heal is noticeable.

Another vote for Electric. In addition to its +end powers, its also immune to -end and -recovery.

I've had a very good experience with Steel Series. Currently have the Sensei 310. Had several Logitech mice die a quick death and won't go near them anymore.

I posted about this in the Bugs section and apparently only actual stealth powers cause reaction time to suppress, not stealth IOs.

This is the current build on my WM/WP brute. Obviously the ATOs, resist cap and epic pools are different, but it should give you some ideas.

In Issue 27, Page 1, the following change was made to Reaction Time: If you are concealed (from Stealth or a similar power) this power will not impact foes unless you are in combat (it will no longer accidentally break stealth) I have the Unbounded Leap/Stealth IO slotted in Sprint and Reaction Time doesn't suppress when I activate Sprint. I have to remember to turn off Reaction Time or I aggro everything. Was the above change only intended to benefit stealth powers but not stealth IOs?

In addition, it has a decent heal that also provides +regen and an endurance discount. Huge resistance to -end and -recovery debuffs. Only big holes are to toxic damage and knockback if you're off the ground.

Interesting. The Unbounded Leap Stealth IO doesn't supress Reaction Time. I have to remember to turn it off or I aggro everything.

Although Reaction Time accepts healing sets, it provides an absorb buff, not a regen buff. Do those procs work in powers that don't heal? BTW, the Regenerative Tissue proc is +regen, not +recovery. Were you looking in the right place in Combat Attributes?

You don't mention whether your team was all 50s and whether they were level shifted, but if the leader was planning to run Kahn at +4 without shifted incarnates and lore pets, he didn't know the TF. Unless you're running it with incarnates and pulling out lore pets, Reichsman is a slog even at lower difficulty levels. You just need massive amounts of damage to overcome his stupid resists and regen. Ran one recently on our weekly SG leveling group. I think we were all lvl 47 and had it set to +0 or +1. These weren't fully tricked out characters, but everyone on the team has been playing since launch. That last fight probably took 20+ minutes.
