Who should I start putting my 5-star skill sig stones into?

IcePick

I currently have Shang Chi as my only 5-star skill champ at max sig. I have yet to roll a 5-star Aegon - but I have a 6 star rank 3 at sig 150 and I don’t think I really need the duplicity of a five star version.

SpideyFunko

Night Thrasher (sig 60)

i have a sig 200 Night Thrasher, no regrets. Super fun and super useful.

Riptide

Falcon sig 120 (have 6-star version at rank 2 but unawakened)

I put sigs into my falcon, helps him nicely

raviXsharma

Crossbones or falcon

Oakenshield

Crossbones at sig 40 (have unawakened 6-star version)

For sure of the options you have listed. Falcon optimal return for sig stones invested is in the 60-70 range. Anything over that you get diminishing returns.

Save for another future champ (kingpin, etc)

If u still use Blade then use them on him, otherwise better to save fr someone like Aegon or KP
Instead of putting it in Falcon better to take the 6* one to R3 sometime in the future
Night Thrasher also needs high sigs but with all the great skill champs we have these days u'll probably not use him most of the time since he requires a rampup to get to his damage

That's actually a misunderstanding. Due to diminishing returns function of critical hit chance, he only gets marginally better after sig 60.

NF for prestige, crossbones if u use him, falcon if u want to finish fights faster, night thrasher if you aren't that interested in endgame content
