Combat explosions, what are they defined as?

But really .... there are detonating combat powers, but no priming ones (and the type of explosion is counted after priming power). Or did I miss something?

So I want to equip cryo ammo or perhaps have my batarian frost someone and then hammer em with concussive shot?

No tech primers from frost or fire?

I'll have more objective point questions later one i am sure as some of these abilities sit is tough to know how they get points. Such as shield boost and barricade.

Thanks for the info, i am getting close with barricade so I'll just play the class as normal with the elec evo.

They may well be, yet fire and ice give Combat Detonations.

Point also remains that this game's detonations are appropriated by the primer, not the detonator. So, if it's Combat Detonations you're after, you can detonate biotics and tech with Concussive Shot all you want but it won't get you any nearer to your goal.

You need fire or ice for that...

lennybusker wrote a very nice combo guide, here:

It's a little outdated now but the core of it is still true. Of note:

As Transcended One states this is for the combos themselves. For some reason the Challenges are the exact opposite. (I suspect shoddy engineering practices; i.e., two different methods written by two different people with no coordination.)

Okay. Don't see why you'd need to apologise, though...

FWIW -- don't think Bioware is the only company with shoddy engineering practices that lead to nonsensical, literally opposite effects sometimes. For example today I overheard this conversation among developers of the website for a major company that you have definitely heard of.

(paraphrased)

Dev 1: I thought that [something about products in a person's cart; I'm being deliberately vague] was checked upon any page load?

Dev 2: No, we decided that was too much overhead. It is only checked when they go to buy.

Dev 3: Wait, are you sure? Because when Dev 1 and I talked to [business stakeholder] she said it should be checked upon page load.

Dev 2: "Should be" or "is"?

Dev 3: Uhh... I'm not sure.

Dev 1: Let's look at the code.

They are still at it BTW. The code is apparently such a mess no one is sure what it does. LOL! But really crying inside.

Also fun to reflect Nullifier shots into them or other Remnant units. And, the Nullifiers don't seem to stop shooting at you!
