Getting Divide By Zero?

[RiverC]

I noticed the older guides suggest that loaded mines + blade + splinter + shielded constructs is part of getting this achievement. However, none of the blades spawned by constructs, either interceptor allies or loaded mines, appear to have shields at all. At the moment I seem to have maxed at about 20 warp shield explosions; something like 8 projectiles + 2 allies + 2 turrets + 8 drones. Since that's only HALF, I'm obviously missing something. Is the achievement out of date, or is there an additional mod that will give not just constructs, but constructs spawned by constructs, your shield?

Have you taken all the +projectile mods you can? Notably, Volley + Fusillade + Barrage + Convergence + Homing Strike already gives Engi way more than 8 Blades, and that's ignoring Twin Strike ^^' .

Another option is to take a similar build with Carrier.

I'll have to see if the carrier swarm drones get shields. If they do, then instead the wild mod that gives you swarm drones when you kill things might do the trick with the eng build

EDIT: answer seems to be: "sometimes" -- lol

EDIT x2: the swarm constructs don't get shields if they are spawned from destroyed enemies. I'd have to look at barrage, but it's only +2 projectiles. Homing MIGHT produce shielded blade constructs, and with barrage it might produce one pair per shot.

Something like 1 in 6 drones is created as standard or advanced, instead of basic. You can tell when it happens even w/o Shielded Constructs, because the swarmlings will have little, faint circles around them when not just a basic model.

Don't take Spontaneous Generation on Carrier w/o Vital Bond! It's a terrible interaction, otherwise, and will badly gimp the lifetime of the drones you generate yourself. But it's relatively easy to get a pretty large swarm of shielded swarmlings, however, using Shielded Constructs/Apex Machinery, as the unshielded ones die off really fast.

Yeah, can't use Vital Bond because that eliminates the shield gear. I did manage to get it with the extra blade drones from barrage (+2) and convergence (+2) with homing strike (+2 per shot). Basically, with one Twin Strike it was 13 projectiles stored, and due to how barrage fires, that's two homing projectiles per shot: 13 x 3 = 39.

Trouble I had with this build is that unless you've got a bunch of exploding shield mods on your constructs, blades + barrage is terribly weak (even more so with convergence.) The right order matters, and I had to get the velocity tree entirely as well. The key to the build is to get shielded constructs quickly because you're going to use your blades as shield bombs. Volatile shields + Tempest break + Reflexive shields got the damage you could do in the thousands, which is what you need. Round 80 boss died in two hits.

Even with that however, the homing projectiles are very short range, so I spawned all my turrets, sat in the corner and fired towards the center. This allowed the homing drones to loop and saturated the map with zipping shielded blade drones, which in addition to generally clearing the map at some point did get a count of 40 or more.
