Build Overview

Crossbows are extremely strong, and so is the Gemling Legionnaire ascendancy! This build deals enormous amounts of damage, it's tanky, fast, easy to play, and can clear all content in the game.

Offense

The playstyle in maps for this build is extremely simple, just run through and blast enemies with Explosive Shot. If anything lives past your initial onslaught, hit them with Explosive Grenade or just dodge roll past and let your Mirage Archer get the job done with their own Explosive Grenade spam!

For bosses, Cluster Grenade, Explosive Grenade, and Mirage Archer (which is also spamming Explosive Grenade) will blast them to pieces quickly. You can shred their resistances with Oil Grenade (automated with Mortar Cannon) for even more boss DPS!

If enemies get too close, you can blind and stun them (or just kill them) with Flash Grenade.

Defense

This build combines Morior Invictus and Constricting Command with campaign bonuses and passive skills to gain a very healthy blend of armour, evasion, and energy shield.

The Gemling Legionnaire's Virtuous Barrier allows you to reach 3000 HP and 1000 ES. When combined with Wind Dancer and Ghost Dance, this is an extremely tanky setup!

Leveling

Use Permafrost Bolts and Fragmentation Rounds to freeze and blast bosses and rare monsters in Act 1 and early Act 2. Once you unlock Explosive Shot in Act 2, switch to it as your primary attack.

Fire Explosive Grenade and Flash Grenade to clear packs and blast bosses. You unlock Cluster Grenade very late in the campaign, and it will obliterate bosses.

Craft Herald of Ash as your first aura in Act 1. Once you reach Act 3, craft Mirage Archer as your second aura and socket Explosive Grenade into it. Turn off Herald of Ash if you need the spirit to use Mirage Archer.

Gemling Legionnaire's first ascendancy point is purely defensive, so you can spec into Tactician and use Supporting Fire instead if you prefer (swapping ascendancies after trials is free, just talk to the nearby NPC). Once you complete the second ascendancy trial, taking Advanced Thaumaturgy with your second pair of points is good if you have 20% quality on your primary skills, otherwise put your points into Implanted Gems and wait to take Advanced Thaumaturgy third.

Gearing

In the campaign, just focus on life, resistances, and flat damage on your armour and rings. Try to maintain a good crossbow with as much damage as possible.

For endgame gearing, you want flat added damage on your rings and gloves, as much damage as possible on your crossbow, and projectile skill levels on both your crossbow and amulet. For defense, you want life, resistances, evasion, and deflection on at least one piece of gear.

The unique helmet Constricting Command (with a roll of "four fewer enemies") allows you to take advantage of several extremely powerful nodes throughout the tree that would otherwise require you to have five enemies nearby. This also allows you to use Defy II support on your skills to gain lucky damage and trivialize mana.

Gemling Legionnaire

Gemling Legionnaire has several extremely powerful bonuses that make it one of the best ascendancies in the game for a wide range of builds.

Virtuous Barrier grants huge bonuses to life, armour, evasion, and energy shield.
Advanced Thaumaturgy provides extra quality bonuses for all of your skills, including extra projectiles on Explosive Grenade, faster detonation time on Cluster Grenade, and extra damage on Flash Grenade.
Implanted Gems adds +2 gem levels to all of your primary skills
Gem Studded gives immunity to critical strike damage and 40% less movement speed penalty while using skills if you have an equal number of red and green support gems socketed. This is extremely easy to achieve.
The small passives on the left side of the ascendancy tree grant an extra 6% skill gem quality! Anointing Paragon allows you to bring all skills above 30% quality, which massively reduces the cooldown of all your grenade skills.
