[spoilers] How do I capture Rell's emotions? (Chains of Harrow quest.)

[Kittenpox]

So I have the Kinetic Siphon Traps (synthesis traps), and I can place it to halt the emotion that's running about.
Then I press 5 to use Transference then try to beam the emotion in the face. But as soon as I begin I'm taking damage from stuff. (I'm using Limbo for the time freeze, so that regular enemies shouldn't be a problem.)

I've done the first quest where I had to capture 3 of them, and used almost 20 traps.
Is there a better way of doing this thing? Or at least one where I don't get hit by CC constantly, and can beam-attack the faces?
At this rate I'll go broke before I can even finish the quest, and Cephalon Simaris *really* doesn't need the credits. :-p

Rell's shadow, the guy you're taking damage from, doesn't really get affected by any warframe ability. You just have to run around and evade him while damaging Rell's emotions slowly. Rell's shadow will stay on your ass for the majority of these missions so it's better to constantly be on the move, utilizing Void Dash as much as possible.

It may be a good idea to make an amp with the Quills at Cetus before doing this quest, as it'll drastically increase your damage output. At least, it felt like that for me. I one shot emotions with the charge shot portion of my amp.

You can damage them with normal weapons

Huh, weird. First time I tried, I wasn't able to deal any damage against them (even with a shotgun - so accuracy shouldn't have been an issue) - so I assumed I needed to use Transference to do it, esp. as it was a requirement for talking to the Red Veil npc.

Been putting myself through trouble needlessly, it seems, when all I had to do was synthesis trap + blast 'em in the face with regular weapons. :-)
Thankyou for the tip!
