Doomfletch's Prism Blast Rain Berserker Build Guide (PoE Delirium 3.10)



Guide Format

This build guide is split over multiple pages, both to prevent it from getting too long, as well as to help you better find the information you are looking for. In addition to the current page, which presents general information about the build and also contains a Leveling and FAQ section, we have the following pages:


The Doomfletch's Prism Doomfletch's Prism Blast Rain Blast Rain Berserker excels at dealing extreme amounts of Elemental damage by stacking a lot of Physical damage, which is then gained as extra damage of each Element. This essentially means that if you deal 100 Physical damage, you will also deal 100 Cold, 100 Fire, and 100 Lightning damage with the same hit. This means scaling a good amount of Physical damage will result in extreme damage gained as extra Elemental.

Although you can choose a different Bow skill for this build concept, we decided to go with Blast Rain Blast Rain simply because it has an amazing single target potential while also maintaining decent clear speed, and it also has full conversion to Elemental, which allows you to run Physical Reflect maps.

The Berserker ascendancy class provides a lot of extra damage in the form of flat Physical damage from Flawless Savagery, the 40% Global multiplier to damage via Aspect of Carnage, and all the speed and damage modifiers the Rage nodes provide.

The downside of the build is survivability and mainly damage mitigation. In order to survive, we depend on our decent Life pool, Dodge and Evasion chance, and the clever use of defensive skills like Steelskin Steelskin and Vaal Grace Vaal Grace.

Build Summary

The build’s only requirement is the Doomfletch's Prism Doomfletch's Prism, which is a fated version of the regular Doomfletch Doomfletch unique Bow. The Bow is upgraded by using the Ancient Doom Ancient Doom Prophecy. You can buy the Bow off the market or upgrade it yourself; the process is very easy and not expensive. Lioneye's Fall Lioneye's Fall allows us to pick up very efficient Critical and Leech nodes and should also be acquired as soon as possible. Besides that, we focus on stacking a lot of Physical damage added to Attacks on Quiver, Rings, Amulet, and Abyssal jewels.

Pros & Cons


+ Hardcore viable
+ Great single target damage
+ Most enemies will not reach you due to your long range and constant Critical Strikes that freeze everything


- Mediocre clear speed
- Bad Physical damage mitigation


Offensively, dropping a single Blast Rain Blast Rain on a pack of monsters will be enough to obliterate it. Staying aggressive will prove to be very efficient, since you will start losing Rage otherwise. Berserk Berserk can be used whenever you need to melt down a tough enemy’ life pool quickly. You can utilize Point Blank whenever it is safe to get near targets.

Defensively, keeping your distance in such a build is very important. Steelskin Steelskin and Vaal Grace Vaal Grace should be used in sticky situations. A Decoy Totem Decoy Totem will distract enemies while you deal tons of damage from distance.

For playstyle, you should stay aggressive and keep in mind you have a lot of defensive power through your utility skills. The build has decent Life and Mana leech, so you will not have any issues with sustain.

As a reminder, we have several guides to help you level up a character.

The character can be leveled really fast and easy if you have a few leveling unique items.

Leveling Trees

This is the early version of the passive skill tree you should be using, as in every other Critical-based build, we recommend investing into Critical nodes after level 55-60.

Useful Leveling Unique Items

As you begin a new character, there are few unique items that can boost your power exponentially. Tabula Rasa Tabula Rasa allows you to have a 6-Linked skill as early as you get the gems. Wanderlust Wanderlust gives a decent movement speed, which will make your leveling that much more efficient. Goldrim Goldrim provides a lot of elemental resistances, this will let you worry less about gearing when approaching certain Act encounters. A simple Storm Cloud Storm Cloud will carry you up to level 40, when you can finally start using Doomfletch's Prism Doomfletch's Prism.

If you are a new player (or if this is your first character for the league), then note that obtaining these items will be very difficult, if not impossible. They are rare drops, which you can otherwise only acquire if you have saved up currency, so do not focus on them too much, and instead simply look for items that match the affix priorities listed in the gearing section above.

Gem Progression

Using Tabula Rasa Tabula Rasa will allow you to have 6-Link gem setups early on, which is why we show such examples below. If you cannot get Tabula Rasa (or another item with a 6-Link), then simply prioritize the first gems in each link provided below.

The Doomfletch’s Prism Blast Rain Berserker is a Bow type of character that excels in dealing extreme amounts of Elemental damage via Critical Strikes. This is achieved by taking advantage of the Bow’s very powerful damage gain mechanic along with the amazing amount of extra damage the Berserker ascendancy class provides.


    Revisited and updated for Delirium 3.10. The build remains very strong with a low investment threshold.


    Revisited and updated for Metamorph 3.9. The build receives a great buff via changes to Blast Rain.


    Revisited and updated for Blight 3.8. The build received a very slight nerf with the Flawless Savagery change. Overall you lose a very little amount of Critical Chance, which does not stop you at all from inflicting immense amounts of damage.
