Explosive Arrow Ballista Totem
Elementalist Build

Updated for Patch 3.20

The Best Crafty Guides by Odealo

The Explosive Arrow is a Bow Attack that sticks the fired Arrow to an enemy and after a short delay, or after it reaches the maximum of 20 stacks of Arrows attached to a single target - it explodes dealing AoE Fire Damage, and all the remaining Explosive Arrows are consumed. The more stacks you have, the higher the damage of the Final Explosion is, so prioritizing the rate at which you can Attack is very important. The usual way to achieve it is to get more Attack Speed, but the most efficient way is to use multiple Ballista Totems. What you have to keep in mind is that you have approximately 1.6 seconds to apply 20 Stacks of Explosive Arrows before they Explode automatically - you can inflict only one instance of Ignite on the enemy, so you have to make sure it is the strongest one possible. 

Elementalist is the go-to Ascendancy for Ignite builds - you have massively increased Ignite Damage and Chance to Ignite by Shaper of Flames, Mastermind of Discord, and Heart of Destruction. The Passives you want to allocate on your Passive Skill Tree are all over the place - you need Ancestral Bond on the top left, Dirty Techniques with Panopticon on the bottom, and somehow fit in the whole Large Cluster Jewel setup. You also use a lot of useful Keystones such as Elemental Overload, Elemental Equilibrium, or Magebane. The most important one is the Ancestral Bond Keystone which raises your Totem limit but disables your direct Damage. To inflict the Combustion Debuff which lowers the Fire Resistance of Ignited enemies you will have to use a Trap Skill which bypasses that restriction. On your Gear, you should get some generic defensive stats such as Life, Armour, and Spell Suppression. To get more Damage look for Attack Speed, Fire Damage over Time Multipliers, and Fire or Elemental Damage with Attack modifiers.

1. Gameplay

Use your Totems to deal Ignite Damage - there is a small delay as you have to wait for Totems to start shooting and then for your Arrows to Explode. Apply a Flammability and Elemental Weakness Curse to lower Fire Resistance and use the Frenzy Attack from time to time to keep maximum Frenzy Charges. To apply Combustion against more resilient opponents use Traps that don't deal Fire Damage - for example, a Lightning Spire Trap. Use Auras such as Precision for more Accuracy Rating, and a combination of Grace with Determination for massive protection against Attacks. Malevolence increases your Ignite Damage and gives you more time to apply all 20 Stacks.

3. Leveling tips

You will have to wait until Act 3 or even 4 before you should start using the Explosive Arrow Balistas, as without the Shaper of Flames Ascendency Notable you won't have much Ignite Chance. To start, you can simply use the Flame Wall and Freezing Pulse and level as a regular Spell Caster. Do not pick up the Ancestral Bond Keystone before you are fully ready for the transition. By that time, you should have plenty of Fire Damage, Maximum Life, and Damage over Time Multiplier Passives allocated on your Passive Tree. Use a very fast-hitting Bow, as all your Damage comes from the Explosive Arrow Gem itself.

5. Final Gems links

[DPS] Explosive Arrow setup
	Explosive Arrow - The primary damage source - it fires an Arrow that attaches to an enemy or a wall and then Explodes dealing Fire Damage and causing Ignite.
	Ballista Totem Support - It makes you summon a Totem that uses a linked Attack instead of you using it.
	Empower Support - raises the Level of supported Active Gem. If you don't have it at level 3, use the Inspiration Support instead.
	Elemental Damage with Attacks Support - one of the best ways to increase your DPS is to simply increase the Elemental Damage with Attacks.
	Burning Damage Support - significantly improves the Damage you deal with an Ignite.
	Deadly Ailments Support - significantly improves the Damage you deal with Ailments, but lowers the Hit Damage.
Situational Support Gems
	Efficacy Support  - increases Skill Effect Duration of DoT effects and the Damage of it, use it if you have a low Attack Speed.
	Ignite Proliferation Support - it spreads the Ignite you caused to nearby enemies so it's mandatory when clearing maps, use it if you don't have a source of it on your Gear.
	Lifetap Support - Skills cost Life instead of Mana and deal slightly more Damage  - great if you don't have enough Mana and good enough Damage.
	Faster Attacks Support - use it when can't get all the 20 stacks on a single enemy before they explode automatically, or when you can't get off-color sockets on your Bow.

[UTILITY] Aura setup
	Grace - one of your defensive Auras, grants a lot of Evasion Rating and allows you to scale it further.
	Determination - this one increases your Armour Rating which is undoubtedly important as you don't have much protection against Physical Damage otherwise.
	Malevolence - increased Skill Effect Duration and Damage over Time.
	Enlighten Support - lowers the Reservation required by linked Auras.

[UTILITY] Arrogance Aura setup
	Precision - grants a lot of Accuracy Rating and a bit of Critical Strike Chance. It has a flat Mana Reservation instead of the usual percentage.
	Arrogance Support - allows you to Reserve Life instead of Mana and improves the effectiveness of linked Auras.

[UTILITY] Flame Dash
	Flame Dash - it is your main traveling Skill used to move from pack to pack and dodge incoming Attacks.

[UTILITY] Combustion setup
	Lightning Spire Trap - You have to cause ignite indirectly - due to Ancestral Bond you can't deal damage by self-casting, and you already use Totems. Lightning Spire Trap seems to have good AoE, it doesn't deal inherently Fire Damage, and should easily Ignite enemies.
	Combustion Support - if you Ignite an enemy with a linked Skill its Fire Resistance gets reduced by 10%.

[UTILITY] Frenzy setup
	Frenzy - hitting an enemy with this Attack will grant you a Frenzy Charge. Use it from time to time to significantly boost your Ballista's Damage.
	Greater Multiple Projectiles Support - adds additional Projectiles so you don't have to aim too precisely.
	Culling Strike Support - kills any enemy under the 10% of maximum Life, even if you can't deal any Damage due to Ancestral Bond Keystone.
	Lifetap Support - spend Life instead of Mana to use this Skill.

[UTILITY] Arcanist Brand setup
	Flammability - it is a Curse that lowers the Fire Resistance of enemies, definitely the best one you can use.
	Elemental Weakness - lowers all Elemental Resistances, but by slightly less than the previous one. You will need sources of additional Curses to apply them both.
	Flame Surge - if it Hits an Ignited enemy, it will create a Burning Ground that deals 25% of the Ignite Damage per second.
	Arcanist Brand - this Brand will cast all Spells linked with it. You will still have to pay the Mana Cost of each Spell.

[UTILITY] Molten Shell
	Molten Shell - mitigates a portion of incoming damage when active; it is more effective the more Armour you have.

6. Gear Setup

Thanks to the Increased Duration of effect from the Malovelanca Aura you will have about 1.6 seconds to apply all 20 Stacks on the enemy for maximum Ignite. Getting enough Attack Speed to do that is the most crucial goal to achieve in terms of Damage. Additional Gem Level affixes will greatly improve the Damage of your explosions -  you should aim to get those modifiers on your Bow and Amulet at all costs. After that look for Fire Damage over Time Multipliers and Elemental Damage with Attacks. Do not add flat Fire Damage to your Attack as it would ruin your Elemental Equilibrium as the Arrows deal no Fire Damage, only the explosion they cause does. Instead, get a small amount of added Cold or Lightning Damage that can be found on many gear pieces and Jewels. Maximum Life, Armour, and Spell Suppression are your main lines of defense.  You will need plenty of Mana Reservation Efficiency to use all your Auras. To comfortably use your Balistas you should have Reduced Mana costs crafted on all your Jewelry - without it, you will have to use the Mana Flask or Lifetap Support. 

(Helmet) Rare Helmet - a Helmet with high Maximum Life and Elemental Resistances is good for a start, but you should look for Mana Reservation Efficiency rather quickly.

Helmet enchantments: Explosive Arrow has 15% increased Attack Speed Explosive Arrow deals 40% increased Damage 30% increased Mana Reservation Efficiency for one of your Aura

Min. requirements: +60 to maximum Life +15% to Damage over Time Multiplier with Attack Skills Optional affixes: increased Attack Speed Accuracy Rating increased Elemental Damage with Attack Skills

(Body Armour) Kaom's Heart - it is a good option at the start if you simply want a lot of maximum Life. It doesn't provide much else, so it should eventually be replaced by a Rare Armour.

Has no Sockets (20-40)% increased Fire Damage +500 to maximum Life

(Body Armour) Rare Armour - a decent Rare Armour can give you tons of defensive value through maximum Life, Spell Suppression Chance, or Aura Effectiveness which would also boost your offense.

(Amulet) Rare Amulet - You can get the increased Level of Fire, Dexterity, or all Skill gems here. Try to pair it up with some maximum Life and DoT Multipliers. If possible, craft the Mana Costs modifiers.

Min. requirements: +50 to maximum Life +50% to Elemental Resistances +1 to Level of all Fire Skill Gems Optional affixes: +20% to (Fire) Damage over Time Multiplier +1 to Level of all Skill Gems +1 to Level of all Dexterity Skill Gems Non-Channelling Skills have -7 to Total Mana Cost (crafted)

Recommended affixes: increased maximum Life Accuracy Rating Fire Damage over Time Multiplier Damaging Ailments deal damage faster Mana Reservation Efficiency Attack Speed

(Jewel) Rain of Splinters - increased number of Projectiles is always good for your clear speed, but it is not mandatory at all.

(50-30)% reduced Totem Damage Totems fire 2 additional Projectiles

(Jewel) Lethal Pride - this Jewel can grant you a lot of useful modifiers, but it is very random and not always worth it. You can use Path of Building to look for the good one.

(Jewel) Watcher's Eye - you can get a lot of Damage with this Jewel if you use relevant Malevolance or Precision Aura modifiers. You can also opt for more defensive ones, such as Spell Suppression or Block Chance.
