When is the next skirk rerun

hi guys So recently, I just noticed skirk existed (quit for a year) and now I’m farming things 4 her… but I’m afraid I’m gonna get tempted by columbina, xilonen, & varesa huhuhuhuhu… I need to know what’s the speculative rerun date!! Like do I have enough time to save up and pull for other characters or do I need to lock tf in and stay vigilant for atleast a c0r0

that’s all thank u guys, but like, she hasn’t had a rerun right???
