Consider helping out in updating the wiki for 3.8.0 - see Path of Exile Wiki:To-do list/3.8.0.

Game data updates to the wiki have been started.


A system has been added that will automatically add divination cards and other items to the item acquisition sections where appropriate. Entries added by this system will be shown as automatic in the item acquisition section.

Some pages will need to be updated to include upgraded_from_disabled=true if they are not eligible for the system.

Some further details on what needs to be done can be found on Path of Exile Wiki:To-do list/Automatic upgraded from and issues can be posted on the talk page.

Vaal Flameblast is a vaal spell that builds up a large explosion to deal fire damage to enemies within the spell area. Unlike regular Flameblast, it doesn't require channeling and explodes multiple times as it charges up.

Skill Functions and Interactions

Unlike regular Flameblast, this skill does not need to be channeled by the caster. It will automatically charge to full stacks while exploding every 5 stages.

The base radius of Vaal Flameblast was tentatively confirmed as 30.[1] This would make the first blast have a base radius of 25, the second of 20, and the final blast of 15.
