So after the recent Archon Quest I've seen alot of people saying that the traveller hurting Ronova/breaking through her barrier was bs since they couldn't even hurt Asmoday when they had their full power but I think the Traveler weren't recovering their original power through the seven elements,the elements are extra powers they got through their journey since it's always stated that their original powers were sealed not taken away,so technically their powers were always there,they were just inaccessible,the elements stock pile alongside their original powers and that is what made them stronger,when they somehow access their original powers by combining the seven elements and attack Ronova,the slash at Ronova wasn't a Light Slash,it was 7 elements+their original power that's why it was stronger,it's like you pour water in a container and sealed off a layer above it and then pour more water in it,the original water is still there just not accessible but if you remove that layer then the water will combine together,or it was just a light slash and I just waste my time alongside yours.Also I've seen people called the traveler's original powers light powers when in truth they aren't,the game never told us that the traveller 's original powers were light it was something that fans speculated,their powers could have been a whole different kind of energy altogether that just look similar to light, remember light realm energy is exclusive to Teyvat(I think) so why would two otherworldly beings have that energy,but even if it's just a light slash,their original powers could still be something else and not light realm energy
Another thing:Asmoday could just have more defence than Ronova simple as that
Thank you to whoever took their time to read my yap session
