Weapons

From early game to endgame, your main weapon that can hugely benefit the Grenadier is the Bombard Crossbow as it can provide you with an additional Grenade projectile. As for your weapon set 2, you can opt to equip any One Hand Mace + Shield combo so you can use Leap Slam and Shield Charge for movement purposes but is not completely required for this build.

List of Weapons

Armor and Accessories

Your highest priority would be to reach the 75% Elemental Resistance cap as this will allow you to take on higher tiers and survive in endgame. Make sure to equip Armor-only Gloves as this will help give you more Evasion once you have Leather Bound Gauntlets in your Passive Tree. Try to get Strength on most of your equipment as well since this will greatly benefit your Maximum Life, especially when you get the Enhanced Effectiveness Ascendancy node.

This build can work with 55 Spirit until you reach endgame, where at that point you will be needing at least 145 Spirit to equip all your Persistent skills.

Jewels

Note: The modifiers listed are arranged according to priority.

Emerald Jewel Emerald ・Increased Projectile Damage
・Increased Attack Damage
・Increased Elemental Damage
・Global Physical Damage
Ruby Jewel Ruby ・Increased Area of Effect
・Increased Fire Damage
・Any Elemental Resistance
・Increased Magnitude of Ignite you Inflict
Sapphire Jewel Sapphire ・Increased Area of Effect
・Increased Elemental Damage
・Any Elemental Resistance

For your jewels, we recommend prioritizing Emeralds as they can maximize your damage by a good amount. The Ruby and Sapphire jewels are still viable for increasing damage but are mostly used to provide Elemental Resistances to help reach the 75% resistance cap.

List of Jewels

Charms

Note: The modifiers listed are arranged according to priority.

POE 2 - Ruby Charm Any Elemental Charm ・Increased Duration
・Increased Charges
・Recover Life when Used

The best charm to slot in would be any Elemental Resistance Charm to help you reach the 75% resistance cap is this is key towards surviving higher tiers. If you have an extra charm slot, you can use the Stone Charm to negate stun effects.

List of All Charms

Runes and Soul Cores

Equipment Sockets
Weapon
Armor

The best slot-in for the Weapons is the Iron Rune for more physical damage, and Soul Core of Zalatl to help recover Mana better. As for Armor, the Soul Core of Citaqualotl can help you reach the Elemental Resistance cap for all elements so try to equip as much of these as you can. You can also opt for either Desert, Storm, or Glacial Runes depending on your missing resistances to reach the 75% cap in case you do not have the Soul Core yet.

Grenadier Gemling Legionnaire Skills and Passive Tree

Active Skills

※ Switch tabs to view build progression: Early Game (Acts 1-2), Mid-Game (Act 3 to Cruel Mode), Endgame (Atlas).

Your main damage skills would be Explosive Grenade for burst damage against Bosses and mobbing, and Cluster Grenade to proc Armor Break so your Flash Grenades can deal even more damage. Make sure to combo these with Oil Grenade and Gas Grenade as consistently triggering Gas Cloud explosions can deal just as much damage as your Explosive Grenades.

Since the Gemling Legionnaire can fulfill Gem attribute requirements using their highest attribute, equipping Wind Dancer, Attrition, and other skills should not be a problem. Once you stop one-shotting mobs, you will need to focus more on damage by then with Fire Infusion and eventually Elemental Focus.

The Wind Dancer will be your failsafe to help survive hits and prevent you from getting swarmed too much, while Attrition is there to proc Culling Strike against Rare and Unique enemies.

Passive Skill Tree

Ascendancy Tree
Ascendancy Group Node
Passive Nodes
1. Volatile Catalyst 2. Colossal Weapon and Devastation
3. Cluster Bombs 4. Volatile Grenades
5. Authority, Polymathy, and Repeating Explosives 6. Beef and Brute Strength
7. Prism Guard 8. -

The Grenadier Gemling passive tree path focuses on increasing your Damage and Area of Effect radius to boost your grenade skills, with Strength and Elemental Resistances to help survive for endgame. We want to buff all our grenades as early as possible so make sure to get Cluster Bombs, Volatile Grenades, and Repeating Explosives immediately.

Once you have most of your Area of Effect nodes, you should start focusing on survivability by taking Evasion Rating, Strength, and Elemental Resistance nodes as this will be important for surviving endgame content.

Keep in mind to take Dexterity attribute nodes to match your skills and equipment requirements in mid-game. Once you have the Adaptive Capability ascendancy node, respec all of your Attribute nodes to Strength as you will only need one stat to meet your Gem attribute requirements.

Grenadier Gemling Legionnaire Playstyle and Skill Rotation

Skill Rotation for Mobbing and Bosses

The Grenadier Gemling Legionnaire build revolves around unleashing all your Grenade Skills to deal huge amounts of damage in a large AoE. The rotation is as follows:

  1. Use Oil Grenade then Explosive Grenade on top to ignite your enemies.
  2. Spam Gas Grenades on your ignited enemies to repeatedly trigger Gas Cloud explosions. You can opt to fire Explosive Grenade in-between to trigger Gas Cloud explosions that did not trigger from ignite.
  3. Shoot Cluster Grenades to build Armor Break.
  4. Fire Flash Grenades to stun and Blind your opponents to help evade hits.
  5. Reposition and repeat the process.

This is a Gemling build so all gems will use whatever your highest stat is to meet their requirements. You'll essentially only ever need enough Dex for your weapon/armor choices, then everything else goes into Strength. Intelligence can be ignored.
