Vaal Skills Changes 3.14

One of the main improvements is that you now get far more souls for Vaal Skills from damaging Unique enemies, so your Vaal Skills will recharge faster against bosses.

Vaal Skill Gems can now only be obtained from a set of specific methods such as Corrupting Gems, Vaal Side Areas, Divination Cards (that specifically grant Vaal Skill Gems) and the Lapidary Lens in the Temple of Atzoatl.

It has made a balance pass on damaging Vaal skills, making them a more interesting choice relative to the Vaal skills that provide ongoing buffs. Damaging Vaal skills in particular to have more reasons to be used by a larger variety of builds.

The uptime for Vaal skills has been improved via various means. Soul generation on Unique monsters has been increased to 6 souls per 2% life lost, with a 1 second cooldown. This is twice as many souls as before.
Damaging Vaal skills have had their Soul Gain Prevention times lowered relative to the duration of the Vaal skill. For Vaal skills that don’t have a duration or ongoing effect the Soul Gain Prevention time is usually just 1 second.
Reduced the Vaal Soul Cost and/or increased the Number of Uses on Vaal Skills that had relatively lower impact per use compared to other Vaal skills.
A balance pass has been made on all Damaging Vaal Skills. Note in all cases these have been buffs, except for Vaal Righteous Fire, which now provides less damage to Spells while active and now sacrifices a larger amount of your total Energy Shield and Life. We felt it was too easy for any Spellcaster to use this skill to get significantly more Spell damage for a long duration, with very little downside. Note the Fire Damage over Time aspect of the skill has been increased, keeping this an attractive option for builds focussing on Burning damage.
It has introduced several new unique items and made adjustments to existing ones to either give higher uptime of Vaal skills at some cost or allow you to utilise Vaal skills more easily on builds that struggle to fit them in.

Vaal Skills Builds

Atziri’s Reign has been improved for building Vaal Skills. It now grants Vaal Skills a 20% chance to regain consumed Souls.
