Unique Jewel Suggestion: Jewels Granting Item Skills Like Illusory Warp

Skills like illusory warp from the star of wraeclast unique could be embedded into a jewel. This could free up a gem slot that would normally be used for a jumping skill like lightning warp or flame dash.

Also the possiblity of other one off skills like those granted by some of the breach uniques.

Illusory Warp on a jewel?
Fire Burst on hit on a jewel?
Lightning Bolt on crit on a jewel?
Raise Spiders on kill on a jewel?
Abberath's fury on a jewel? Just as an example, not a good one.

I love this idea, however I can easily see it becoming very overpowered.

There would have to be a big downside...

Perhaps a keystone where you can only do damage through your jewels? :D

You waste a jewel socket to get an unlinked, probably utility, skill.

There won't be many cases where it's going to beat a 40% whatever damage jewel.

The useful damage spells could have their chance to proc toned down, or have its level scale with number of jewels. This could also be its own class of jewel like the 'primordial' jewels and be limited to one across multiple types or some type of jewel set to get the effect.

Effect could also be scaled. 1 jewel gets you a +5 levels on the lightning bolt on crit skill it grants with +5 levels per jewel. 6 Jewels could give a level 30 skill, but it's unlinked.
