0.5.5 Fubgun Flameblast Oil Grenade

Updated on Sep 12, 2026
Sep 12, 2026

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 the fully min-max version of the build, reaching dot cap or near it (35m dps). It's also extremely tanky with 85k armour, 50% chance to evade and 3.5k life. The effective hit pool is around 200k

This variant is very expensive and requires a jade/granite Mageblood

Mageblood is required for this variant to properly work. You want Jade/Granite/bismuth (can have 1x dupe or 4th flask can be amethyst, quicksilver or gold flask are all good options). Granite/basalt also works, you wont just have 50% evade.

As for your gear you Want high armour helmet for Emergent Vigour, higher armour gloves for Leather Bound Gauntlets and boots can either be pure armour or hybrid arm/evasion.

You want "Armour applies to elemental damage" on every single piece, so ideally 40% on gloves/boots/helmet/body armour. Combined with the passive tree you should reach over 200% of armour applies to elemental damage.

You should be around 80k armour with a proper setup and around 45-50% chance to evade.

You do need some spirit on your amulet, so you can run both Mana Remnants and Arctic Armour. Remember you can use Soul Core of Azcapa on your crossbow to help with spirit. Charge Regulation is another option if you find a good way to solve endurance generation.

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.

Rite of Passage the spirit is Bear, but ox is also a good option.

Jewels:
At this point you should be making 3x prefix Ruby jewels, Ideal jewels:

Prefix 1: Ignite magnitude
Prefix 2: %increased armour
Prefix 3: Increased elemental damage or increased fire damage

Suffix 1: 40-60% increased effect of prefix modifiers.
The 2nd suffix doesn't matter as there is no good 2nd suffix on a ruby jewel for this build.

---For a speed variant try this
1) Use Absent Amulet with cast on dodge, while you cant quality the skill yourself, global quality modifiers will still apply. Giving you an extra 1m dodge roll
2) Use Decree of Flight boots or Ghostmarch
3) Use a Quicksilver Mageblood (can also take more MS nodes on tree).

This setup is extremely fast and really nice for boss rush strats or travel maps.

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.

This was my first time building a character based on a build, and it all worked out—thanks for the build.

But my FPS drops really badly. (RTX 5070TI)

update, hopefully someone can help, i've got the endgame items, it was low invest didn't spend more than a few divs, but for sure either something is wrong either we're missing some deffences, i've got 76% each element deff and 50 chaos res, 2.5k hp 1k ES, 200 ward lvl 81, the only item left is the helmet the lvl 80 crown which doesn't send me any confidence it will make diff since i have quite a good helmet already. Waystones lvl 11 rare, always something oneshots me trhough all hp,es all of a sudden wihtout omen of resurgence i die like a bug. sure it's nice to melt everything but at this point i may try another build before i invest in a mageblood here
