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.
