A couple of things.
First, you can modify how your skills work from Options->Gameplay.
There is something called ‘Skill Activation Styles’.
The options are:
Standard
Quick
Instant
Please note that whatever you choose…it will be for all characters.
Standard is the default, but I go with ‘Quick’.
This means that when you activate Shadow Fire Pillar, you keep the button pressed down, and then upon release you activate the skill. (I find this better than Standard which forces you to click twice)
Next, I mostly play Meltdown, and I play a minion-clearing, buildable-destroying, shard-gathering, buildable-building build. (Which also works pretty well in Incursion)
So I clear minions (usually want to up my skill damage), gather shards, and build stuff.
I typically look to have the most damage done, most minions killed, most buildables built. Sometimes I end up with a lot of kills, sometimes with only a few, it really depends.
Here are the skills I go with:
I used to go with the push-back on Nullify, but Blind seems to be the better option now.
I like to recharge my shields on Nullify, so if I have to, I can run into a situation, then Nullify out while getting some protection.
I prefer Preamble of Pain at 4, because the minions will normally stay in it and then I only have to worry about landing 1 shadow fire pillar.
If you want more ‘easy’ BB Kills you can go with Renaissance at 5, but otherwise either of the other choices are good…though I tend to go with Prognstication more times than not…as I like that after Nullify I usually can instantly cast Shadow Fire Pillar ago.
At 6 and 7 I choose to increase Shadow Fire Pillar damage and skill damage.
At 8 and 9 I reduce Nullify Cooldown and Shadow Fire Pillar cooldown…and then in PvP always go for the mutation.
For gear:
I just got an almost perfect Codex Fragment from an Archive run…so I might go with that in her build. (Skill Dmg + Max Health). I will probably pair that with a 0 shard generator (- reload) and a 0 shard wrench. (-reload).
Skill Dmg, Cool-down, movement speed, & Shield/Health seem to work best for her…and if you go buildable (which I think works best) you probably want to at least go with a shard generator…and if you fully commit or have a legendary, go with a 0 shard wrench. I saw someone mention Firmware Update as a legendary (Cooldown + Sprint) and that is a really good one as well.
As far as playstyle goes, here is what I have learned:
She is really squishy so you have to hit and run. Always stay on the edges and don’t get down and dirty in the fray, because you can get focused down fast…especially at higher levels.
I normally will start with a pillar, then nullify to get my pillar cooled down, pop another pillar, finish with Paradigm if I have it/need it, then jet out…get more shards, build more buildables, and then jump into the fray once again.
Also, if there is an Ambra on the other team…I have found that I just have to stay as far away as possible. With Ambra’s upgraded range on her fire beam, along with Ambra’s movement speed…it is hard to get away if she gets a lock on you. You rely on mobility to stay alive and the auto-aim of that beam completely negates that.
