I run a Kayla, Aidan, Dante, Octavia and Corvus/Guus team. Kayla is G75 while Dante, Octavia and Corvus are G60. Aidan is G55 and Guus is G50. On whom should I invest my Gylphs? Thank You.

Current Gylphs Levels:-

Kayla - G75. Dante - G60. Octavia - G60. Corvus - G60. Aidan - G55 Guus - G50.

I also use Somna and Iris depending on some match-ups. Iris is on G50 while Somna is on G40.

So yeah, where should I invest my Gylphs? Thank You.
