Build Overview

This is a build guide for purely progressing through campaign. The idea is that you swap to another endgame build at that point.

This is one of the fastest leveling builds for Witchhunter, Tactician, and Gemling Legionnaire. It's the leaguestart version of the build that I used to win multiple Act 4 Boss Kill Races, and finish the campaign in 3:38.

Build Variants

This will be your setup for the majority of Act 1. Your goal is to get to level 14 by the time you start fighting Geonor, so that you can use Gas Grenade.

Don't spend any Regals, Alcs, Runes, or Exalts until Act 2. You're saving them for the level 16 Varnished Crossbow

Weapon: Click here for a very detailed guide on how to get great weapons throughout campaign. Having a great weapon versus having a bad weapon drastically changes your damage, so I strongly recommend reading it.

Boots: Movement Speed > Resists / Life / Armour

Rings/glove: High flat damage (preferably lightning damage for shock) > Resists / Life

Helmet/Body Armour: Resists / Life / Armour

Amulet: +# to level of all projectile skills > Life / Resists

Belt: Rawhide Belt with Resists / Life / Armour

Your first Level 1 Uncut Skill Gem that you get from Renly will be Explosive Grenade and then you must pick up the Skill Gem in Clearfell to cut Frost Bomb.

Make sure to get your first support gem from Areagne in The Grelwood, and cut Multishot I for Explosive Grenade.

First Level 3 Skill Gem (The Rust King): Upgrade Explosive Grenade

Second Level 3 Skill Gem (Lachlann): Flash Grenade.

Third Level 3 Skill Gem (Crowbell): Pounce

Upgrading priority: Explosive Grenade > Flash Grenade

Tier 1 Support Gem Order:

  1. Multishot I + Elemental Armament I for Explosive Grenade.
  2. Multishot I for Flash Grenade (which you'll put on Gas Grenade)
  3. Elemental Armament I for Gas Grenade (when you're level 14)

How it Plays

In early Act 1, use Explosive Grenade and Fragmentation Rounds to clear trash monsters. You'll drop Fragmentation Rounds by the time you reach level 6. Flash Grenade is used to help clear trash monsters, and stun bosses. If your gear is strong enough, flash grenade can one shot entire packs.

At Level 14, your trash-clearing rotation becomes: throw Gas Grenade, then Explosive Grenade to detonate it. Throw them ahead and run past so mobs follow into the blasts.

For bosses, cast Gas Grenade, then Explosive Grenade, and continue throwing gas / explosive grenades on cooldown. Gas Grenade has a limit of 6, so before you start using Bombard Crossbow, you can cast Gas Grenade twice per Explosive Grenade (rather than once). Once you get Oil Grenade, you should throw one out before continuing your usual rotation.

From level 52 for clear, cast Cluster Grenade, and you will one shot the screen.

How it Works

Ascendancy:

This build doesn't require any ascendancy to clear campaign / T15s, so if you're planning to swap to another build in endgame, you can go straight into that.
