Take it or Don't take it

I have a level 27 Dual Weapon/Dark Armor scrapper. Have not played either set before. My dilemma is with Dark Regeneration. Looks like a good heal (30%), quick cast (1.17) and recharge (30s) but only heals self, requires enemies around and has a big Endurance hit (33.8). Since this toon is already starved for Endurance I skipped this so far. I can fit it in later after I get Conserve Power and Physical Perfection but would have to drop either Combat Jumping, Maneuvers, or Assault to do it.

So my question to those with experience, is it worth it or should I stay with the three powers I listed and use other means of healing?

Take it take it take it!

Slot it with 2 rech 1 acc and 3 end red if you're using SOs

Take it and get rid of Maneuvers and Assault until later.

It's the defining power of Dark Armor, without it you're more or less just a weaker version of Fire Armor.

TAKE DARK REGENERATION AS SOON AS YOU POSSIBLY CAN!

It is the only self heal in the game that can take you from .01 HP to full.

As far as slotting goes, if you slot only 1 IO in the entire build, make sure it is the Theft of Essence Chance for +End. I went from losing a third of my end bar when I used Dark Regen to occasionally GAINING end from the addition of that IO.

It's one of the best heals in the game. That's 30% per enemy it hits, and unslotted. In other words, in most normal situations, Dark Regeneration is a FULL heal. It's a hit point reset button. You may not use it MUCH before you have your endurance more under control, but you'll still be better off taking a blue and getting a full heal off of that endurance than taking several greens in a row. And when you can afford it and fit it in, the Theft of Essence proc is the way you better manage the heal's endurance consumption. So yes, take it.

TAKE
Now to get back to reading the second half of the OP's post and all the others.

OK, thanks for the advice. I altered my plan and will take it at 28 dropping Combat Jumping that didn't add much anyway.

Thanks again!

Just wanted to say that the Theft of Essence proc slotted there was some of the best advice I received, made a huge difference. I sometimes hit it just to hopefully get a bit more on the blue bar.

Also ditto on taking it earlier via respec if you drop down to run TFs or whatever.

And the more dead enemies you have, the less you need the heal. I suppose it would be good for farming, though, where there is always a plentiful supply of both.
