In the latest patch of Forbidden Sanctum 3.20, The Explosive Arrow Ballista is a great all-rounder build, especially for the league start, as it can quickly kill bosses by dealing colossal damage done by ignites. The build also ignites massively applied on mobs with the help of Ignite Proliferation Support as it spreads to enemies around the first target.
Attention matters for this build to truly shine, so you need to keep on the mechanics. For more in-depth analysis and how to farm currency quickly, remember to check out the news page of Mmogah.

Skills Breakdown for Explosive Arrow Build
Let's look into the primary skills you need for this build to work properly.
Explosive Arrow
This skill is our primary damage dealer, which your build should always support with Ballista Totem Support, hence the name of the build. The skill applies a fuse to the arrows where they land; they either explode after a set amount of time or if multiple arrows are applied. So the more arrows stack, the higher the damage dealt. Ballista shortens this duration and helps to apply more fuses, thus dealing tons of damage.
Frenzy
Ranged attack skill that stacks Frenzy Charges with each attack you do, buffing DMG and ATK SPD with each stack.
Auras
We will stack four auras for this build.
Determination – Granting you and your allies armor-reducing DMG from PHY DMG.
Grace – Staple Evasion gem.
Defiance Banner – This skill will further enhance the armor and evasion rating of your champion while lower the enemies' chance to crit.
Precision – Improves your accuracy and enhances your chance to crit.
Brand
Essential for single target DMG when you are fighting bosses after getting attached or branded on an enemy, it periodically activates the skills linked to it, such as Flammability and Flame Surge. Flammability here reduces enemy RES, while the Flame Surge places the Burning Ground effect under enemies and damages those who walk on it. This skill link combo helps you to apply ad forget and worry about other important things or surviving.
Molten Shell
A defensive skill that enhances more the more armor you have. The skill has no cooldown, so you can assign it to your movement skill to be applied instantly when moving. You can swap this skill for Vaal Molten Shell in the end game, enhancing this buff and giving you a short invincibility.
Flame Dash
Staple movement skill for this build.

Final Comments
Remember to learn more about the Path of Exile Forbidden Sanctum 3.20 and its new mechanics. In the meanwhile, the following is the summary of what we just discussed:
The Ballista combo with Explosive Arrow is a wonderful build to enhance your speed during map clears. A tremendous all-around build overall.
The main mechanic of this build to deal damage relies on ignite. You proc ignite by placing turrets around enemies that shoot arrows. The faster these arrows shoot, the quicker ignite explodes, dealing massive damage.
While the Ballista is doing the damage dealing for you, you can move around the map to better place these turrets allowing you to stay away from damage.
If you love min-maxing, this build rewards you greatly.
