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

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.

List of Armors

Accessories

As for your Accessories, we recommend equipping two Prismatic Rings to help you reach the 75% Resistance cap much easier to take on high tier maps. Keep in mind that this does not affect Chaos Resistance so you will still need Chaos Resistance modifiers to survive against poison effects and chaos damage.

List of Accessories

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
・Damage Penetrates Fire Resistance
・Increased Magnitude of Ignite you Inflict
Sapphire Jewel Sapphire ・Increased Area of Effect
・Increased Elemental Damage

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 specific modifiers that can benefit certain skills.

List of Jewels

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.

POE 2 Beira Beira's Anguish Dousing Charm

・23% Chance to gain a Charge when you kill an enemy
・Ignite enemies in presence as though dealing Fire damage equal to 25% of your Maximum Life when used

We recommend equipping Thawing Charm or Antidote Charm depending on your current Act as many of their Bosses have specific elements that can help with your survivability. As for endgame, try to pick up or trade Beira's Anguish Dousing Charm as this works great with the Bleed Ballista Tactician build due to the high Maximum Life it has.

List of All Charms

Grenadier Gemling Legionnaire Skills

※ The Support Gems' priority are arranged in a descending order. The first one being the most important and the last being the least crucial.

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 Tree Progression

Passive Nodes
1. Remorseless and 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.

Mobbing and Bossing

The Grenadier Gemling Legionnaire build revolves around unleashing all your Grenade Skills to deal huge amounts of burst 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 and 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.
