This version of Frozen Legion causes the statues to step forward as they use Frozen Sweep. Adding a bit of range to the attacks makes it easier to overlap Frozen Sweeps.

The Volcanic Fissures erupt 3 times in an effect similar to Vaal Volcanic Fissure. The strength of this gem largely comes down to the Fissure pattern and how many projectiles overlap.

Normally Bladestorm creates Storms based on your Stance. But the Transfigured version creates both storms regardless of your Stance. Having the Sand Storms mixed in with Blood Storms adds a good bit of mobility and clear. However, losing additional Storms from quality is a steep price to pay.

This version of Raise Zombie allows you to drop Zombies on your foe. A Physical Spell which scales off of Minion damage and even counts as a Minion dying? Nothing broken to see here, folks!

If you've ever said to yourself "I enjoy Flame Dashing with an Echoing Shrine only to return to my starting location" this is the skill for you. This one seems like a bit of a meme.

The Transfigured Firestorm skill deals damage through multiple small Firestorms instead of 3 larger Firestorms. From the look of Firestorm of Meteors vs Firestorm of Pelting, the Pelting variant is focused on raining down a widespread swath of destruction , whereas Meteors is all about single target.

The other Transfigured Firestorm Gem revealed replaces the smaller storms with a gigantic flaming bolt. The base damage is massive so this could be an ideal choice for Traps, Mines, or Cast On Critical Strike Support.

This version of Blight is spread by your Contagion. If you combine Blight, Cast while Channelling Support and Essence Drain both DoTs will spread through enemy packs.

Normally Frost Bomb is a supporting ability, used for exposure and to reduce enemy Regeneration. The Transfigured version turns it into a damaging main skill, creating a blast after a short delay without any cooldown.

This version of Detonate Dead cannot used player created corpses like those from Desecrate or Unearth. 34.5% of a Corpse's maximum life is one big boom, but it'll be difficult to capitalize on this for bosses.

A Transfigured Blade Trap which uses Two Handed Swords instead of the normal One Handed weapons. There are a lot of powerful 2h Unique Swords like Voidforge and Rakiata's Dance.

Killing blows with Double Strike cause Impalesplosions similar to the Great Old One's TentaclesUnique Gloves. A great way to add clear to your Melee build.

This version of Barrage adds additional Horizontal Projectiles, these most likely work like the old Threshold Jewel and most won't strike the primary target.

Now your Blink Arrow Clones use a skill similar to Rain of Arrows in place of their default attack. This greatly increases their ability to quickly clear an area without the need to scale projectiles.

Your Blink Arrow Clones use a skill similar to Elemental Hit in place of their default attacks.

Animate ranged weapons instead of melee weapons. Lingering blades you target with Animate Weapon become bows to unleash a barrage of death upon your foes.

A version of Arc whose beams split towards targets instead of chaining, similar to the default behavior of Exsanguinate.

This Transfigured Animate Guardian Gem was revealed in a recent teaser and uses Smite of Divine Judgment.

From the Teaser gameplay, it's difficult to tell what Smite of Divine Judgment does, hopefully the level 20 gem is revealed soon!

Normally Ball Lightning travels forward dealing damage every 150ms. The Transfigured version is stationary and regularly zaps foes which could be valuable for Trigger builds who normally stand too close to foes to take advantage of normal Ball Lightning.
