Disclaimer

A necessity to the build, Rain of Splinters Rain of Splinters has now become a corrupt only gem. This makes it a little harder to achieve in SSF environments but it shouldn’t be impossible to obtain through trade. The odds of obtaining it yourself through corruptions are currently unknown & thus unpredictable.

Introduction

Explosive Arrow Explosive Arrow has been hyped up incredibly hard by a lot of people this league.
Getting some input and backbone from popular and reliable content creators such as Ziz and Crouching Tuna I decided to write up a guide about this insane-looking leaguestarter for 3.17

Mechanics

The mechanics of this build, unlike often suggested, are actually fairly simple. You’re looking to stack as much explosive arrows on a target as possible to abuse the more damage multiplier on the gem. This is achieved by playing a Totem build, as they all apply fuses to your target. Given the damage scaling is so outrageous, this build gets to focus on stacking a lot of defenses. That’s also why I chose to write about the most durable version available. For variants on the build, generally Hierophant or Elementalist, I refer back to the abovementioned youtube content creators who have guides on the Hiero & Elementalist counterparts.

While this build is an insane and obscene powerhouse in the lategame (and has overkill amounts of damage even while starting mapping) it does have one little problem. It’s relatively annoying to level, even more so on a champion. You’re going to be leveling as a melee build until level 28 (with something like Shattering Steel Shattering Steel or Splitting Steel Splitting Steel) which might be tedious but once you kick of with EA, as long as you stack enough attack speed, you’re going to be blasting. Getting an early Quill Rain Quill Rain will smooth the leveling process by a lot once you swap over to EA.

When you start getting to the endgame, you’re just going to spam out ballista totems when you’re running around in the map. Once on a boss, make sure to drop totems & hit them with Frenzy Frenzy to generate charges & curse them.

Disclaimer: Make sure to find a single roll of Lighting or Cold damage to attacks on your gear or jewels to activate Elemental Equilibrium. Make sure you don’t have a single source of “Fire Damage to Attacks” anywhere!

Build Viability in Numbers

This is where I’ll rate the build in numbers. The lower the number the worse I actually think the build is in that compartment.

  • Durability : 9.5/10
  • Damage : 9.5/10
  • Playstyle : 7/10
  • Gearing : 7/10
  • Complexity : 5/10

Path of Building & Skill Tree

You can find an optimized Path of Building here. Every build I release will use the community fork of Path of Building, which is maintained and updated in a much more regular fashion than the original one. You can find PoB’s Fork, by LocalIdentity, here.

If you are not comfortable with Path of Building, we also have a PoE planner for you. Do note that PoE Planner does not support Cluster Jewels and some specific unique jewels and it is highly recommended you install Path of Building to follow builds most optimally.
