0.5.5 Fubgun Flameblast Oil Grenade

By Fubgun

Build Overview

This is my Flameblast / Oil Grenade build for 0.5.5, trying to focus on speed and clear, as this build already has a ton of damage built in. Opting for a Cast on Dodge setup with gemling for a speedy setup.

You'll level as the very powerful grenade merc setup and once you reach lvl 52 you'll swap to Flameblast, you cannot swap any earlier because Flameblast is a lvl 52 gem.

Build Variants

This is a higher budget version, the lvl 85 version can already comfortable clear all content. You can push even farther if you opt for a full armour/mageblood setup to be extremely tanky.

Gear: It's really simple and easy to gear this character, you just want Life/resist and rarity on every single piece. %inc fire damage is nice on rings, but it's a small boost and not needed. Also keep in mind, strength is always a good suffix because it provides life, you have a lot of free affixes on this build.

You're also going to stack both ward and life, to get the highest amount of ward you want to use Tier 1 bases of any hybrid base. I prefer ES/Armour or pure int bases, just to give us the highest pool. Armour is not that effective until you start actually starting it so just focus on pure life/ward

Morior Invictus (life) is a great chest option, specially if you can pickup a 5 socket one with life per socket, combined with Perfect Body Rune you can get a ton of life. Other good options with life would be all resist, chaos resist or spirit.

If you need spirit you can also use Soul Core of Azcapa in your crossbow.

Blackflame is another item you can go for, we bypass the downside and get a massive ignite magnitude. It's a good early pickup, but eventually you would want to replace it with a triple rarity gold ring. If you do use black flame, make sure you also use Withering Presence.

Amulet: You can go for a Cast on Dodge Absent Amulet amulet, as this will provide even more dodge roll distance with our global quality, use the same links as the regular cast on dodge setup. The other option is using a Gold Amulet, which will be a lot cheaper as well.

Dousing charm: This is pretty important and a must have. If you get ignited, that ignite can spread to your oil grenade and brick your snapshot (you'll do 0 damage). So make sure to always use this charm.

Anoint: Paragon is the best anoint.

At this point you can start making your 5 prop jewels, these will give a massive amount of damage:

Ideal 5 prop:
Prefix 1: Mag of ailments you inflict 15%
Prefix 2: Ignite magnitude 15%
Prefix 3: Spell dmg or elemental damage (% armour or %Es can also be good if you scale your build for those).

Suffix 1: +1 prefix modifier
Suffix 2: Damaging ailments deal damage 7% faster

You have 1 decision you can make here, you can either go for a Temporal Chains/Blasphemy setup or use Mana Remnants for Khatal's Rejuvenation, as this will provide more CDR and near infinite mana. Keep in mind the blasphemy setup will require more spirit to use.

If you opt for Blackflame you'll want to use Withering Presence with Prolonged Duration II and Chaos Mastery.

Because we're gemling, it's important we balance our gem colors for Gem Studded, it's not hard to setup you can just equip any crossbow skills and than just use any support gem of any color until you have all 3 equal. This will also count the gems in your weapon swap.

-How do I get more skill slots?
With Unset Rings and Augmented Flesh. You can snapshot skill slots. Put on your rings/amulet, equip your skills and than take them off. While you wont be able to use the skills, they will still count for stuff like Gem Studded and Essence of Virtue.

To balance Gem Studded, just make sure all the gems at the top are equal, but exclude gems in your staff skill as those do not count towards the total amount.

Passive Tree

main:

set 1:

set 2:

Because you travel so far on the tree, your attributes should generally be pretty free. You need high enough intelligence for Flameblast, but it shouldn't be an issue to solve all attributes as this build.

You'll want every jewel with flammability magnitude, these can roll on ruby jewels or sapphire jewels. Ailments inflict damage faster is also a strong stat.

Ascendancy order:
Essence of Virtue -> Advanced Thaumaturgy -> Implanted Gems(int) -> Gem Studded

How it Works

Frequently asked qustions

  • Issues with oil grenade not igniting or not dealing damage
  • 1) You cannot have flat fire damage or extra fire damage anywhere on your gear (the only exception is your staff).
  • 2) Make sure your weapon swap is setup correctly. Flameblast on weapon set 1 and oil grenade on weapon set 2.
  • 3) If you're doing a map with burning ground you have to takeout tornado from your cast on dodge and replace it with another spell (like frost bomb).
  • 4) You have to press oil grenades into flameblast and your flameblast has to hit a target.
  • Keep in mind on bosses, you don't have 100% chance to ignite and it could take 2 flameblast. Higher damage/higher flammability magnitude does help with this.
  • 5) You're getting ignited and it's overriding your ignite on oil grenade, make sure to always use a Dousing Charm
  • 6) Headhunter is not good for this build and the buffs it provides can brick your ignite.

-How do I get more skill slots?
With Unset Rings and Augmented Flesh. You can snapshot skill slots. Put on your rings/amulet, equip your skills and than take them off. While you wont be able to use the skills, they will still count for stuff like Gem Studded and Essence of Virtue.

To balance Gem Studded, just make sure all the gems at the top are equal, but exclude gems in your staff skill as those do not count towards the total amount.

-Where do you get all of your gem quality from?
5% from Fox Idol
5% from Paragon Anoint
5% From Amulet suffix (desecrated modifier)
6% from gemling small ascendancy nodes
20-23% from Gem quality

This will give you in total 41-44% quality.

40% quality is pretty important as it's a breakpoint for some skills, Arctic Armour armour will gain 1 stage (and another +1 stage if you get gem lvl 27, for a total of 8). Quality is also a massive damage multiplier for Flameblast.

Получил 52 уровень. Настроил дерево умений как в гайде. Проверил, чтобы нигде, кроме посоха не было дополнительного урона от огня. Убедился, что смена оружия работает правильно. Проверил все камни умений. Но огненный взрыв отказывается зажигать масляную гранату. Что я делаю не так?

Totally understood skillbuild until [DoT Cap].

What are those Infernal cry, Incendiary shot?.. Is tornado still useful or gone to be a support gems placeholder?... What are 9 skills for use and what are 4 for placeholders now? Why 2 of those are without support gems at all?

To balance the skill gems type you'll need to equip some skills, so you can equip unset rings and other equip that will allow 3 more skills. After that. You need to balance 16/16/16 of Str, Dex and Int gems, so it doesn't matter which skills you use to balance everything.
