As I said she was referring to him to be able to surpass power of gods ( AS ) and move Freely in AS nothing for me shows that Dimaria use Chronos in that fight ( unless we will get flashback which I doubt ) and him resisting it because his END he was designed to surpass the powers of Gods from Mildean in order to bypass curse that Zeref have..Lel kek it's not offtopic.
Well regarding the discussion.Dimaria was surprised that someone was able to move inside Age Seal and then she added "You are telling me his power surpasses that of Gods".And the only God that is connected with Dimaria is Chronos.

Now why did Dimaria say that his power surpasses that of gods after seeing him move inside Age Seal.So it's natural to say surpassing Gods(Chronos) is one of the ways to resist Age Seal.
For me, she only meant here AS not Chronos TO ( but it's all and the same in the end :P )
And as I said I can't prove my point and you can't prove I'm wrong until we will see flashback that Chronos TO was involved in that fight for me not ( Dimaria words can be interpreted both ways and how the Room looks like after fight shows that she never use Chronos for me )
.I also agree with that.
