Harkness

Given how cheap it is, I think your last build is fantastic.

I'd never prioritise all of those Typed Defs over Recharge, but it's undeniably a beast of a corr. The term "Squishy" doesn't really apply anymore!

Other than obvious, expensive tweaks like the Numina unique and LotGs, the only thing that I can see is maybe trading in an EndMod from Stamina (your End is fine and you have Transference) and slotting the Steadfast KB in ID. You won't need it at level 50, but if you mal down to play SFs, then you'll notice the difference.

Wow, that's a lot of Typed Def! Well done!

I'd push to aim for the S/L softcap before Energy, simply because the majority of attacks are Typed S or L.

I always aim to get a kin to perma-hasten with two applications of siphon speed, and that's usually possible without resorting to purples.

You also skipped Pistols, which is your (natively) highest DPA attack.

Ouch. No.

Mez resistance is one of those options that's hard to build up to significant enough levels to really change your survivability. It's not that it's a bad idea, it's just that there's stronger options.

As a DP/Kin, you're probably living in/near melee, but you lack much direct mitigation. Since you'd gone for Scorp Shield anyway, I'd strongly suggest going for a S/L softcap build.

I'd also aim to get Hasten up to perma with two applications of Siphon Speed.

Pistols is your highest DPA attack. You're not stacking Suppressive Fire with anything else (like Web Cocoon), so I'd probably skip that and grab Pistols!

$30 for DP? I wouldn't.

It's fun and flashy, but it roots you horribly and does meh damage. It's decent AoE, but not brilliant. I've found it weak as an ST-damage set. Purely as a Blast set, I'd put Fire, Archery, Ice, Sonic, Rad and maybe even Dark and Energy over it.

Demons are really fun. I haven't played any other MMs, but Demons are quite potent, and I'm enjoying the heck out of them. They're potent and pretty!

Both are suffering from Flavour of the Month syndrome right now, and I've seen the call of "lvl x team lf anything except DS" on a semi-regular basis.

Mostly agreeing with the above: All of these builds are going to be beasts, but have a hard time with End. I think all of them are going a bit overboard with non-S/L Def, and it's an extremely expensive build to have such a big problem in it. Of course, you can chew blues all the time, but I'd suggest focusing on End in Drain Psyche if you're not going to get Stamina.

You don't offer many requirements, so I'll share the S/L softcap build that I'm toying with at the moment. Recharge is so-so compared to purp builds, but it hits the S/L softcap and Endurance shouldn't be a problem at all.

If I'm reading you right, your question is: "I'm running FA, can I skip Accuracy IOs in my other powers?"

The complicated to-hit equation:

NetToHit = (InherentAttackAccuracy) * (1 + AccuracyEnhancement) * [ BaseToHit (75%) + ToHitBuffs - ToHitDebuffs - (Defense - DefenseDebuffs) ]

FA raises your InherentAttackAccuracy by a unenhanceable 20%. IO set global attack bonuses affect this same part of the equation.

FA also raises your base (75%) To-Hit by an enhanceable 4.25% (up to ~7%). It also has a 55.36% Resistance to To-Hit Debuffs.

Accuracy IOs slotted in powers affect the AccuracyEnhancement score.

So, as you can see, they're affecting different things.

Personally, I've never been a big fan of leaving FA up all the time, esp. for Corrs who can easily run into Endurance issues. Unless you're a rad with perma-AM, I'd usually save it for AVs and Arachnos only.

If you want more detail (and a more precise answer to your question), I'd suggest you post this over in the Scrapper forum. They've had FA for longer, and have several secondaries that make Endurance so plentiful that FA can be a constant. Also most of the hardcore number crunchers pay the most attention to that forum.

The general rule seems to be: De/Buffs from different powers or from different casters stack. The same De/Buff from the same power and caster do not stack.

There's a few exceptions to that rule, but I'd doubt if DP broke it.

I'm not sure what parts of this build is concept vs effectiveness. I think you've spent a lot of time and effort going for Ranged Def with little thought to much else.

Having played Dark/Dark with, at one point, Super Speed, TP, and Flight, I found that I used TP to travel outside mishes and whenever I was immobbed or fleeing a team-wipe, Hover made TP travel a bit safer and gave me some help in combat but it was ultimately awkward in switching between TT's wide/short cone and NF's narrow/long cone. I never used Flight except for fun. Hover was for combat, and TP was so much faster for outside travel and SS was so much faster for inside travel that Flight simply didn't have a place.

I use SS+CJ now, which makes the TT/NF switch easy.

I initially went with Mu Mastery for concept reasons, but I think you made a mistake in skipping Soul Storm. Not only is it one of the most pretty powers in the game (and it gets a lot of 'what power is that?' comments from heroes in co-op zones), it doubles well with Pet Gaze to lockdown EBs and even AVs. A Devastation Hold Proc in Dark Blast can be fired between those two Holds and get all but the immune.

Personally, my experience with Dark Embrace was that it provided some desperately needed protection at a hell of an Endurance cost. With your slotting, it's essentially unuseable and a waste of a power slot.

You have a LOT of underslotted / set mule powers: Dark Servant, Shadow Fall, Dark Embrace and Darkest Night could all use help if you actually plan on using any of them. Health is also underslotted, Stamina could use more if you plan on using any of your toggles.

I really, really loved the look of the Fortuna Mistress. But she was often slow to respond, and then prone to drifting too far towards the next mob. In comparison, Fluffy is a battlefield genius, attacking where needed and almost-never aggroing a mob you didn't drag or drop him into.

So although I was sad to see her go, the switch to Mace Mastery yielded stronger results. The Disruptor didn't look as cool as the Fortuna, but it had better brains. It attacked more readily and survived longer.

Scorpion Shield puts building for S/L Def on the table, potentially even the softcap (although a Dark/Dark doesn't really need to aim for softcaps).

Focused Accuracy means you don't miss. You probably won't need it unless you're fighting Arachnos or an AV, but it's nice to have it for those occasions.

Web Cocoon is a second hold, although it's not as quick or anywhere near as pretty as Soul Storm.

If you can go with Mace Mastery and it won't hurt your concept, I'd say go for it and build for the S/L softcap.

If you remain with Soul Mastery and you like hover-blasting stick with the Ranged/AoE Def idea, but bring up the AoE. Ideally, you'd want to try for 35% Ranged and 20-25% AoE Def (with your Acc debuffs effectively bringing you to ~45% Ranged and 35% AoE Def). Putting triples of BotZ in your travel powers (Hover, Fly, Recall Friend, etc.) will help you considerably with that goal.

I'd strongly urge you to get Hasten and to give Fearsome Stare an Accurate To Hit Debuff set (pick the set with the Def bonus you'd prefer). FS slotted like this can be as potent an Accuracy debuff as Darkest Night but it can be slapped on every mob at a much cheaper End price (in addition to Fearing them).

I'd slot Tar Patch with more Recharge Reduction too, so you can hopefully use it with every mob.

Personally, I find that Dark Servant slotting almost a crime. Fluffy is too good to set mule him!

I'd seriously look again at Shadow Fall. It easily yield 5.6% Def to everything, which is better than any set bonus. And it extends that Def to Fluffy and any other pets or team-mates around you.

A stealth proc in Hover or Flight (or TP, Sprint, etc.) can double up with SF to make you invis. It's so easy to have that up for a Dark/Dark that it seems a shame not to.
