This is a pretty straight forward Engi build which gives the Engi as a gun user a bit more edge than the usual drone heavy or striker builds. It utilizes Rapid Fire and near max Beacon in combination with Hastebot, concussive Crash, Spidermines and a minimal Drone setup.
I wouldnt call it an exceptionally beginner friendly build but it is also not super niche. Engi just needs more custom auged items and therefore paladium investment if you want to be good with guns.
First here is the skilltree:
Now the planner is outdated and the final few points can be placed differently depending on your taste and since the Engi often uses Cast weapons you might have more points to distribute.
The main line goes like this:
-Max out Rapid Fire, Hastebot and concussive crash
-put the minimum of points into the drone to reach tactical mode, medpack retrofit and repairmode
-distribute the remaining points between Beacon and Spidermines
The main attack combo is first concussive crash, whichs stuns alot of enemies which often bunch up on your drone and does very good damage. Since the mobs are stunned now, your drone doesnt take that much damage while it shoots its 3m splash projectiles and you can safely follow up with Spidermines and then a full blast of Rapid fire into the lot. There is not much that can survive this. On heavy HP elites or Bosses beacon comes first.
For easymode clearing you get away with gunning and spamming concussive crash and dropping in some spidermines here and there. I often use them to kill stuff i run past.
Spidermines are very situational to use and you dont really spam them. They need to be positioned well so they hit the right target and not wander off to kill some zombies.
The drones skills come into play when the going gets tougher like in St Pauls, or Catas. There you need to repair it often and activate medpack to boost your resistance. Besides the heal the shield recharge comes in handy and prevents being getting affected by status effects so often.
Tactical mode even if it is questionable if it increases the rate of fire is still usefull as the drone shoots more reliably when it is not running around like a chicken.
With this setup the engi can really push forward and make use of movement speed and implement a quicker than usual gameplay while he can still allways retreat behind his little tank.
He has alot of aoe and supports it with rapid fire from a far and point blank (see weapon choices below).
You could use Bomberbot and Ghostly strike instead of Inhibitor bots and concussive crash. However Bomber cost more power and we already use alot. Also the aoe on concussive crash is bigger AND it is easier to use as you can see where it is dropping.
Perks: All stats (start identifying items early for the Willpower Perk after 2000 identified items)
Expertise: I prefer Crit, Elemental Attack, some Elemental Defense, HP or Power/Reg if needed
Now this is the hardest part. The engi wants to have Minion Damage everywhere but he also wants to use MM style damage gear. This means either compromises are being made or it gets expensive quickly as MM gear ususally doesnt have Minion damage.
AND you are likely to run into stat problems unless you get some stat augs aswell. You will realize that every point counts with Accu being the main issue. So here we go:
-Helmet: Eye of the Maverick or Sombergs Guise with +1, godly would be a minion damage aug too. You can get away with a Heavenly+1+Minion damge Helmet or a good Legendary with some damage +1, Minion damage and maybe a stat - a good Helmet is the hardest part.
-Torso: Techa Battlecore is definitly the best choice for this build. Massive Minion damage, Accu and userate to get that concussive crash spam going.
Those two are the most important items. Out of the following you need to make sure one item has shield penetration, so that status effect from you, the bots and the drone gets applied even if mobs are shielded. One needs to have movement speed and most likely one has to have ALOT of stats.
-Shoulder: Techa Bladeguard are a very good choice if you can aug Minion Damage on them, They got damage, caste damage, crit damage and physical damage (lookout for 5-7%). They use alot of stats and dont bring any - so hard to equip. Advanced Scout Shoulderplates also need a minion damage aug but they bring armor penetration, +AA and can come with some increased damage aswell. Sues Steadiers are ok too though fall behind. I’d rather take some legendary Cybernet Shoulderpads over them. If they come with Minion Damage and stats they will be fine.
-Arms: One would likely say Duellos of the Duelist. They come with 3% Crit, +Acc and can have increase damage aswell. They need a Minion Damage aug too and it won’t be the highest one because of the ilevel. Now the Techa guards are normally a neglected item but in this case they are not that bad. They come with alot of stamina which we also need, added damage and just 1% crit. But we are not getting that high critdamage values anyways. Getting more health for the drone can also free up some drone options. Needs a Minion damage aug too but here it can get 40%+. A legendary cybernet item with stats and Minion damage is a cheaper option.
-Belt: Either Techa belt with Minion damage aug or a Cybernet legendary. I would invest into the techa after all other items.
-Legs:Now the Techa unique is ok but doesnt bring anything needed over a legendary Cybernet and needs a Minion damage aug. Legendary ones can come directly with Minion damage and offer the same damage and crit. If you happen to aug Minion damage on good Lanzers Longrunners with shield pene this opens up some options as you can tick off the shield pene and movement speed issue.
-Boots: There are two options, either Techa Deathstompers with Minion Damage as they are the only “damage” items that comes with shield pene. Needs the minion damage aug again and doesnt have Movement speed which is an issue. I prefer at least one bigger movement speed affix somewhere so this would lead to the dye kit in that case which is suboptimal since there are other good dye kits. Here some compromises have to be made, hence i mentioned Lanzers. Or you get Quatermaster Boots with shield pene, of course Minion damage and Movement speed.
You see it gets a bit more tricky on the Engi and decisions between damage, minion damage, shield pene, Stats and movement speed have to be made wisely.
-Trinket: depending on your Minion damage, either a Fulcrum Scale for boosting your and the minions damage or Squadros Ring (preferably a phase one)/Dark Master to boost your own damage.
-Dye: Highly dependant on your gear. If you dont have Movement Speed i would go for Wasp if you dont have Shield pene go for Twilight, otherwise either Scorched or the Crit Multi one.
Since we are using Rapid Fire, we should go for slower weapons as Rate of Fire caps somehwere between 700 and 800 and we get a 3,35 multiplier on rate of fire with Rapid.
I allways have two sets of weapons, one for single damage and one for AOE.
For single damage you can use either Railguns or Jackhammers (with Gaus being the Meta atm). I use a combination of Nantos and Reapers Hellrail and they work nicely together. I stuff ele damage/phase mods into the Reapers so they apply Phase with the field. The Nantos get one ignite mod and the rest damage. They dont have splash and ignite is only needed for bosses anyways. Both weapons start at low ilevels so can be auged a bit more cheaper.
They utilize Rapid fire nicely in that they apply Phase,Shock,Ignite and Poison easily due to the high rate of fire.
Make sure you have some elemental damage in there because those mods need willpower and you need alot of power.
Now for the AOE set we look out for Global weapons. Grenade Launchers are good but we have a new gem and that is a global XM272 Thermocannon. This thing is nuts. It comes with 12m splash and when fired with Rapid fire it can take out the whole area between the stairs and the temple in a Rift. With rapid fire, it is Fire and Forget. I heavily invest in phase too, it looks cool when suddenly all goes purple and it also supports the following concussive crash when mobs are phased.
I want to test out the new unique Withering Tube but didnt come across one so far.
The third set is a cast set with two 1handers that have either hastebot or drone skills on them. With Drone skills beware that you have that set selected if the drone is out and you go from a station into a map.
For the Drone i dont go for anything fancy or hard to come by because there is still a rare bug where your Drone loses its gear. Therefore i go for a widely availabe Mirs Anger as Armor (it comes with +9/10 AA) and as a weapon i use a 4slot Infernous. I use Aladdins Final Wish (what else can i use) but you can also use a global one. Infernous is imho the perfect Drone weapon, due to its hard homing nature and high AOE (as opposed to the Leech Launcher). Put your Drone in tactical mode so it shoots more reliably. It adds alot of damage to your arsenal and you dont run into stat problems even in the minimal setup. It is ramping damage, so it needs to build up, be aware of that. But even if it kills some low hp mob the projectile wanders on and applies damage to the next mob. Not much is wasted.
It is a little less in DPS than the Leech Launcher which is widely used but way better when the Drone gets swamped due to its AOE.
A few words on the Drones stats. Dont go havoc on assigning your Attribute points because until now they cant be reskilled! I waited until i could fit the Mirs Anger and then only put in a cheap Cabalist gun until i was ready for the infernous. And then i only put in a few points to make it work. We are running a minimal Drone setup so attr points are tight. The Majority of points i put in when my Char hit 50.
Here we go. I think the build is very versatile and uses alot of the Engis arsenal. It is skill use heavy but has alot of very satisfying buttons to press
(gonna put up a video soon)
