----Work in progess!—
Hi greatest adventures of Grim Dawn world. My name is SneakyBadAss (not real ofc ) and i would like present you my custom made Saboteur build.
Research time (13 hours)
Developing time (4 hours)
Polishing build (2 hours and counting)
Writing this build (2,5 hours and counting+ forum 3x kick me off).
First lets ask a question. What is Saboteur? For me Saboteur is person who have specific skill to sabotage by explosive, traps, poison, informations etc. Also he cant bee seen or hear.
Im the type of person who don’t like walking in someone footsteps. Especially in term of theorycrafting or builds in videogames. Ok enough talk lets talk about build.
So origins of Blackrock Saboteur? Its a Cthonian aspirant who was banished for experimenting with explosives and fire. Usually leading to human sacrifice being shredded over all walls and precious blood lost in flames and black powder. He promise revenge for what they did. After many years roaming around infested world, he met woman. Nightblade (actual name). They live and fight together for years. But one day, when he return for revenge and fought with his mister, he fell in to trap. Rushing home only to see his wife laying in pool of blood. Beside here was note -Take those blades and never forget. Love you always, Nightblade.
All right now really in to actual build. It consist of 80% demolisher and 20% Nightblade.
First weapons: You should always carry dual wield one hand weapon or rifle/crossbow. You could double pistol, but this is not build suited for.
Auguments. Always enchant Slam on one of your melee weapon. Its a huuuge bonus in to damage and mainly, its a catalyst for celestial power, but about this later. Other arguments are all on you, but i would prefer something with fire/chaos/poison damage.
-----------------------------DEVOTION-------------------
I know its usual talking about devotion before masteries and skills, but this build is sustained on specific devotion, so i find appropriate to show them first and then what skill you should actually use to get glorious combinations.
I will mark elemental damages and resist with specific colors, so you can distinct between them more easily.
All right, lets get dirty. As title say, we focus on Fire+ Chaos and some Poison/ acid damage (later, in devotion tree, poison and acid is second biggest bonus damage).
Our core build consist of 20 devotion points :
1.Crossroads
2.Guardian Gaze
3.Flame Torrent
4.Jackal
5.Edritch Fire
You might Ask why Guardian Gaze but trust me. This is the most important devotion tree. Without this, whole build will collapse, it doesn’t seems like it, but ill explain later. Our goal is to get 5.Edritch Fire on main attack ASAP. You should have this unlocked on lvl 40-42.
This is stats you get when you finish core build:
90% chaos damage
40% poison damage
50% fire damage
10% acid damage
10% spirit-not important
8% all damage
8% chaos ressist
+18 offensive ability
As you can see, we now have really good basement for upgrading, dominated by chaos damage, which is what we want. But now it will be more difficult.
All right what to do now?
Depend on your items. If you equip consists mostly of fire an burning damage, you are going for Meteor Shower
If your equip consists mostly of chaos/poison/acid damage, you are going for Abominable Might
Dont worry, both pats are 100% similiar, its only way how to get faster in to your prefered Celestial power. In the end you will get both. Also Meteor Shower is easiest to get, but you will lack of chaos/poison/acid resist. And it will be less powerful.
Ok, you Choose path of Meteor Shower. Your path will be faster, but less powerful.
This is what you want:
6.Fox
7. Hydra (This is why you need Guardian Gaze. Without it, you would not have 3 ascendant points for hydra, thus cant aquire ultimate Celestial skill).
8.Meteor Shower
9.Fissure (This is where you get the biggest fire/burning bonus damage for Meteor shower).
10.Abominable Might
Those are stats you get when you obtain 8.Meteor Shower
140% fire damage
90% chaos damage
80% burn damage + 100% increased duration + 16 burn damage for 3s
45% bleeding damage+ 8 bleed damage for 3s
40% poison damage
28% all damage
23% chaos ressist
20% fire resistance +3% max fire resist
20% slow resistance
20% pierce damage
10% acid damage
10% spirit
10% crit damage
+5% movement speed
+68 offensive ability +8%
+35 cunning
As you can see, we exchange Chaos damage for shit ton of fire and burning damage…like you want it. It will be crazy boosted by 9.Fissure Main fact is, at this point. (finishing Meteor Strike) your builds will be same.
Now lets a look at 10.Abominable Might path
This is how you want to build it:
6. Hydra (This is why you need Guardian Gaze. Without it, you would not have 3 ascendant points for hydra, thus cant aquire ultimate Celestial skill).
7.Fissure
8.Fox
9.Abominable Might
10.Meteor Shower
And of course here are stats
170% chaos damage
120% poison damage
90% fire damage 6-8 fire damage
65% burn damage +30% incresed duration + 15 burn damage for 3s
50% acid damage
45% bleeding damage + 15 bleed damage for 3s
40% vitality damage
38% all damage
25% fire resistance
20% pierce damage
20% poison resist + 3% max poison ressist
20% slow resistance
10% spirit
8% chaos ressist
5% casting speed
+250 health
+113 offensive ability +3%
+35 Cunning
Yes, nearly 200% Chaos damage and 120% poison damage. Without items or abilities!
Do you wanna see primary stats when you complete Devotion tree path? I know you want 
Here it is:
170% chaos damage
120% poison damage
180% fire damage
145% burn damage + 130% increased duration
I think this sums up perfectly, what this build is about. Burn everything with poisoned fire from the hell
Now to the fun part
