POEGuy's Siege Ballista Hierophant PoB & Gems (Poe Mirage)
Path of Building – Passive Skill Tree
You can find an optimized Path of Building (PoB) here
League Start Info here: PoB and Guide for League-Start
Every build I release will use the community fork of Path of Building. You can find PoB’s Fork by LocalIdentity, here.
If you’re new to Path of Building, we have a guide available here.
Remember that inside, you have three Skill Tree progressions. Start with the one closest to your level and work your way up. The Skill Tree nodes need to be unlocked in the suggested order.

*To simplify things for new Path of Exile 1 players, I will name the item slots where you will socket the gems.
But remember that in PoE1, you can socket these gem setups into any item that has the correct number of linked sockets and the appropriate colors.
Body Armour
Siege Ballista (Apply 20% quality! Big DPS boost!)
Increased Critical Damage Support
Elemental Damage with Attacks Support
Added Cold Damage Support (Aim for level 21 as fast as possible; flat added Cold Damage greatly boosts our damage.)
Inspiration Support
Enhance Support Level 4! (
Faster Attacks Support for Low and Medium Budget)
Bow
Frenzy (Keep this gem at Level 1)
Manaforged Arrows Support
Cast On Critical Strike Support
Frostbite
Frost Bomb (Keep this gem at Level 1)
Ensnaring Arrow (Keep this gem at Level 1)
*The bow setup works as follows: Summoning totems spends mana, which triggers
Manaforged Arrows Support and causes
Frenzy to activate. When Frenzy hits an enemy and critically strikes, it applies
Frostbite,
Frost Bomb and
Ensnaring Arrow. Everything is fully automated!
Boots
Dash
Second Wind Support
Blood Rage
Enhance Support (Optional)
Gloves
Portal (White gem; can be inserted into any socket color!)
Cast on Death Support

For the gems to work, you don’t want a 4-link setup for the gloves! (Check the image)
Helmet
Purity of Elements
Grace
Enlighten Support (if you’re on a tight budget, buy a corrupted one to reduce the cost!)
Imbued Gems
In Patch 3.28, we received the ability to imbue our Skill Gems with level 1 Support Gems. Here is a list of the most impactful imbues for our
Siege Ballista Skill Gem:
To imbue, we will use a Coin of Skill (green) on a level 20/20 uncorrupted gem.
Considerable DPS Boost (ordered from best to worst):
Returning Projectiles Support,
Cold Penetration Support,
Hypothermia Support,
Momentum Support and
Faster Attacks Support.

Remember always to level up your gems and apply quality which can provide significant benefits for your gems. If you’re new to the game, pressing and holding down the ALT key on a gem, you can view and read its quality effects! You can apply quality by using
Gemcutter's Prism. You can also buy low-level gems with quality already on them from the trade website, or run Labs for the Forge rewards.
Siege Ballista grants you one extra totem! You can reach that level by using a level 21/20 Siege Ballista skill gem and a
Briskwrap with one of the following corruptions: +1 to Level of Socketed Gems or +2 to Level of Socketed Projectile Gems. Later, you’ll switch to a crafted rare body armour that also brings Siege Ballista to level 22 (Check the crafting timestamp from the video guide).
- For Patch 3.28, we will prioritize imbued gems over having one extra totem!
Enhance Support level 4 is the best pick for our
Siege Ballista gem setup! Quality on the Siege Ballista gives us a significant increase in attack speed! Its three times more powerful than using
Faster Attacks Support.
