Toxic Rain DoT Trickster - All Content - Build Guide (The Forbidden Sanctum 3.20)




Since Toxic Rain Toxic Rain is one of the most popular builds both in league-starting and later environments, it is one of those guides that we felt could not be missing. Toxic Rain is an interesting skill gem and is able to be built around in multiple ways. This guide will focus on scaling the Damage over Time aspect of the gem, or the “pods” as people tend to call them. This means you have an incredible Area of Effect and clear speed as a result while maintaining boss damage that is capable of killing every boss in the game in under 30 seconds.

Mostly when a guide starts off like that, you end up with a build that has 3,000 Health and no underlying defensive mechanics, but this build is a Trickster and has a significant amount of investment in defences, so even though you’re able to clear fast, kill every boss in a fairly timely manner, you’re still incredibly durable, and with the tremendous amount of recovery that Trickster provides, there are very few things that can effectively hurt or kill you.

Map Modifiers to be Avoided

The build can handle any modifiers I would say however you should be weary of combinations that have double damage modifiers.

Playstyle, Mechanics & Strengths

As mentioned beforehand, Toxic Rain Toxic Rain has different ways to be scaled and we chose the Damage over Time. So, the way Toxic Rain works is that it fires a number of arrows when it gets used. These arrows do “on hit” damage, which doesn’t scale much with levels, but more so with added damage from gear, supports, and other such things. We do not scale the on-hit damage at all in this build. When the arrows land, they create “Pods” on the ground. These pods explode when they expire, dealing on-hit damage again, so that’s useless for us. However, while they are on the ground, they deal Damage over Time, which is what we scale.

When talking about the pods, it is important (and mandatory for the skill to even work) to know that they can “shotgun”, to use PoE’s most favourite term. This means that overlapping pods deal overlapping amounts of damage. Therefore, it’s optimal that we stack as many pods as possible. This means that duration is a stat we don’t mind having, as it makes the pods explode more slowly, and thus deal their DoT longer. On top of that, Attack Speed is another stat we really enjoy, as it means more pods get created, which results in more overlapping pods and thus in more damage on your target!

Because of those mechanics, and our scaling Attack Speed, this build does not require an expensive +3 bow with additional modifiers that are incredibly hard to obtain! It uses a Quill Rain Quill Rain from start to finish! So, after looking for Attack Speed, Skill Effect Duration, and Damage over Time modifiers, all that’s left for the build is defensive layers!

First of all, it picks up Spell Suppression nodes & affixes, which combined with the Trickster Ascendancies, grants up to 50% Less Damage taken from Spells. It combines this with a decent chunk of Life as well as all the defensive layers you can get through Auras as it runs the trifecta of Defensive Auras (Determination, Grace, Defiance Banner). It also has access to a decent amount of Chaos Resistance which has become more necessary over the past leagues. To top this all off, Diadem carries your sustain really hard through Feast of Flesh.

Passive Skill Tree, PoB, and Gem Links

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 Tree 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.

More information about the Passive Skill Tree, as well as all the Gem Links can be found on our dedicated page.
