Favorite Gem

I just wanted to ask what is your favorite skill gem and why?

For me I would have to say that I have two favorite skill gems.

The first being Righteous Fire and the second being Leap Slam.

I love Righteous Fire because its damage based on HP rather than attack allowing for more defensive builds rather than offensive while still providing a decent damage output. (Not to mention the spell bonus damage!)

I also love Leap Slam purely because of its traveling potential and not to mention the ability to use it with dual Brightbeak for traveling speed. (Makes up for my lack of movement speed!)

Lightning warp because is the best skill for open boxes with old computers

Flame Surge. I just like the mechanics of the skill and that it feels like a melee spellcaster kind of thing.

And of course RF. The builds that can be made with it are always fun to theorycraft.

I also like Vaal RF and Power Syphon (just because it looks great).

Vaal Summon Skeletons is the coolest skill I think.

conversion trap

For usefulness, whirling blades. I like to go and I like to go fast.
For fun, SRS or Vaal Summon Skele. Both fill the screen with minions that just crush things and fight for you.
(sorry I cheated on your question)

Aesthetics - arctic breath
Imo best designed - frost blades

Favorite Gem?: Power Syphon.

Reason?: Looks Awesome.

Lightning Arrow because I 1 shot uber with it.

RedGemsOnly!

Also... Flame Totem #1 Why... because it's a cheap and easy build, it does all map mods fearlessly (ok maybe chaining is a lil scarey) and you can play the build from lvl 4 to 100 and witness it's power growth.
