[Saboteur] Arc miner: from budget to all endgame content

25/06/2018: added new POB with latest gear + leveling tree
24/06/2018: added uber atziri run
20/06/2018: added gameplay video

Pros:
-build scales very well with gear upgrade and can achieve millions of shaper DPS.
-Can run all mods and do ALL content (including HOGM, chayula etc.)
-Fast clear speed
-Good defense (5k+ hp, 1k+ ES, MOM = 8k+ EHP)
-Really cheap to get going

Cons:
-need get use to the playstyle
-cannot facetank anything since no instant leech. It's possible depending map mods or encounter but you will need to make the right call based on your experience.

Uber atziri (die once in trio because trying to kill Q'ura last for the challenge)

more to be added... Uber elder down with this build

POB will give you the damage per mine/trap, so you need to multiple this by the number of mine/trap you lay/throw per use and then multiply again by how many time you can lay/throw mine/trap per second.

I take the saboteur nodes in that order:
1-Pyromaniac for life regen & immunities
2-bomb specialist (for speed)
3-Demolition specialist (for speed)
4-Born in the shadows (very OP node, 10% less dmg & avoid 50% of melee hit)

In HC I have leveled 2 GC miner in the past and I tried different order. I thought taking Born in the shadows (4) before demolition specialist (3) is safer but if you know what you are doing it's not necessary and you can take the speed nodes before it. I tried both scenario and succeeded in doing uber lab either way.

I always took pyromaniac first, it's really good especially the shock immute to avoid damage spikes.

-6L dps setup: arc/vaal arc + remote mine + minefield + trap/mine damage + increased critical strike + lightning penetration (last gem not needed with shroud of lightness as it's included in the body armour)
-helm with +1 mine (see trick and tips): CWDT lvl1 + Immortal call lvl1 + increased duration + phase run lvl3
-Gloves: spell totem + detonate + increased duration + totem resistance
-Boot: CWDT lvl20 + ice golem lvl20 + enfeeble lvl20 + free choice (portal, ...)
-Main hand: movement skills
- shield charge + faster attack + fortify on brightbeak
- Flame dash + faster casting + arcane surge with shimmeron.
-Off hand: CWDT lvl3 + enfeeble lvl7 + vortex lvl1

The only one flask that I believe is really required is Lavangia's spirit. It's too good to pass on for MoM build especially with high mana cost skill like mine.


For the rest it's up to you but I also like blood of the Karui because it will boost the regen from your mined detonated recently and it has the highest life/sec with a bonus to put you on full life at the end of the effect. This build doesn't really need instant life as it has high eHP.


Then, an anti curse + anti freeze flask is a must (with increased duration mod is even better). For instance:


Finally, anti bleed is recommended for incursion league (see trick and tips)

The damage of this build is high enough you don't need unique flask such as atziri's promise. It's better to use utility flask with QoL/defense.

The tree focuses on:
- as much life as possible
- MoM and bit of mana boost
- all power charge nodes for shimmeron
- Effective dps node

Tree

Latest POB = 1.6m shaper DPS with no flask, only PC which is guarantee

There is still room room for improvement with for instance 4 x GG mods jewels but after defeating pretty much all endgame content I have no interest and prefer have fun with another character now.

Old POB

You can adjust of course with your preference but the ultimate goal of my build is explained below.

Overview of all the gear pieces


Use weapon swap for clear speed / boss kill

For clear speed I use brightbeak with shield charge.

For single target dps I use weapon swap with dual shimmeron


Use call of the brotherhood to freeze and shatter everything

The main reason to use this ring is for safe mapping. Porcupines can be very deadly and shattering is the most effective mechanism.


Since we convert some lightning into cold, lightning penetration gem lose effectiveness. To solve this we are using Shroud of the lightness. It gives ele penetration for all elemental damage and a tons of perks for the build (ES, life, mana, temporary damage immunity)


Specifically for uber elder

Kaom's root is just too OP for not using it in this fight. So I swap for it + essence worm for more dps with Wrath gem and I also have another ring I didn't link simply to re-balance resist at 75/75/75.



The lack of movement speed is a bit annoying because the only movement skill I have with Shimmeron is flame dash and you can't spam it. So you have to know the fight mechanics and use it carefully. When Elder is spamming his tentacle, you better swap weapon for brightbeak and spam shield charge.

Arc mine is so strong that you don't need much to start red map tier. The budget version would consist of:
-Brightbeak (1-3c depending on the time of the league)
-a 5L (2-3c) or tabula (10-12c)
-the rest doesn't matter, just life and resist.

So for 10c you can have all your gear and clearing very fast maps.

In terms of upgrade I went with the below:
-+1 mine shaper helm asap (+25% more dps)
-shroud of the lightness + call of the brotherhood (makes mapping safer. If you don't have shroud you would lose a bit of dps on the cold portion and it wouldn't penetrate as much as lightning)
-Shimmeron x 2 (farm elder in T6+ map asap, I got one myself, in incursion it's 4-5EX)

Now you had a look at the gear, here are some trick and tips:
-The +1 mine comes with a downside. It's because the mod is mine support/+1 mine and the mine support is going to support any spell skill gem in the helm slot:
- CWDT setup will not be working
- Totem or golem can still work but it would lay first a mine and you need to detonate it to get the totem/golem.
- Phase run is a spell but you can still use it !
- So what should you put in the helm ? Before having shimmeron a good setup is shield charge + faster attack + fortify + culling (Quality provides attack speed). Once you have shimmeron, my setup is CWDT + IC + duration + phase run for additional defense. I'm thinking to sneak in blood rage before IC gem so I can proc "Soul of Arakaali" but so far I prefer to have "Soul of the Brine King" to avoid stun lock.
-Normally for mine build, bleed immunity flask is not necessary because the life regen can over heal it and you will never get 20 stacks of blood corruption. However in incursion league I died a few times in incursion/temple because there is this pyramid applied stack of bleeding and the range is long, so I recommend one during incursion.
-The build lack naturally of dexterity and Strength (for brightbeak) so you will need to sneak in a bit wherever possible.
-Flame dash main hit can crit, hence avoid flame dashing into a pack otherwise the degen from Shimmeron will put you in danger. The burning ground effect though cannot crit since only hit can crit.

-+1 mine on shaper helm
-Scale crit multi with good jewels. Jewels are always very expensive when looking for life and good dps mod.
-Look for extra chain which is flat 15% more dps for each additional chain (helm enchant, and lvl21 arc)
-Get additional power charge to boost shimmeron bonus (amulet corruption)

- When leveling, use alternate weapons to level additional arc skill gems so you can try get 21/20 later with vaal orb. The +1 at level 20 is huge dps boost because of +1 chain (15% more dmg) and the regular damage scaling.
- At level 12 you can swap from whatever you were using to arc + mine
- You can use whatever trap you like until level 40-50 also in parallel as it's really Op since 3.3 (I love bear trap as it increase as well mine damage).
- focus on getting 4L and then 5L asap.
- I'd take MoM very late once I have a good mana flask like Lavianga's spirit
