5 star generic gem. (Who is worthy?)

Comments
But Starlord is one of the most worth it champions to use a gem on.
I’d hold that gem for Blade, Medusa, Voodoo. Maybe Ice..
SL
GP
GR
Are the only possible choices. GP doesn’t need her awakened ability. GR benefits greatly but also doesn’t need it. SL needs to be awakened if using him for any content.
Once you are an endgame content player SL’s usefulness will be very limited. So I’d weigh how much content you have left where SL is needed.
Star Lord - Still king of LOL which means he'll get you a 5* class awakening gem, a 5* generic awakening gem, and 12 T2AC for LOL exploration
Archangel - Still useful in high tier AW and a beast in quests and tough LOL fights like Electro/Spidey/X-23. Watch Idelest's AW videos to see how well AA still does in high tier AW.
Voodoo - Great unawakened but godly when awakened. When awakened Voodoo gets 50% ability accuracy reduction for both offensive and defensive abilities, power burn, power drain, power gain, massive spirit poison damage, and increased regeneration/spirit poison duration.
Blade - Unlimited regeneration
Other less deserving champs include:
Gwenpool - Best defensive ability reduction in the game
Morningstar - See dreamin34's YouTube channel
