True. But if we look more into what actually happened, you can see a significant difference. God Serena used 4 spells to take down the 3 Gods of Ishgar + Jura. Not only does this equal to 1 spell per person (due to the damage from the attack dispersing between Hyberion, Wolfheim, Warrod, and Jura), but the 4 Wizard Saints are already superior to TO Chelia + DF Wendy. Hyberion is easily on TO Chelia's level (if not above) and with the other 3 mages, they can surpass DF Wendy without much competition. Also, we have to take into account that TO Chelia was completely drained of energy after using Heavenly Gathering of Clouds while God Serena didn't even break a sweat using 4 attacks. That tells us that this guy wasn't even using his strong attacks, let alone the fact that he was probably holding back too.
First of all, he would've used more spells since they were already attacked off-screen.
Second, God Serena used his spells against
all the Gods of Ishgar together, not one on one. But after all the spells he used none of them was out of the game. It wouldn't be different if he fought one God of Ishgar. The amount of opponents doesn't matter for someone as God Serena who uses high AoE spells.
God of Ishgar > DF Wendy
God of Ishgar > Base Chelia
But,
TO Chelia > God of Ishgar (since she soloed a Spriggan and the Gods of Ishgar couldn't).
TO Chelia defeated Di Maria after Heavenly Gathering of Clouds. She didn't need to use it a second time.
I don't put too much emphasis on Slayer Advantage like others do. In my eyes, you have to have the power to do considerable damage to your opponent to begin with for Slayer Advantage to even help (especially in a one-shot).
Agreed.
This can be debatable. For me, it's pretty obvious. Jura already has more durability than DF Wendy. The other 3 Gods of Ishgar should exceed that and rival TO Chelia. Hyberion most likely has higher defense than any of them. We can't accurately compare the two situations because that would lead to erroneous conclusions. God Serena is more powerful than Dimaria. So the fact that you believe the 3 Gods of Ishgar + Jura have lower defense than TO Chelia + Wendy just because they were on the ground doesn't mean much. Especially since, Chelia and Wendy both suffered major injuries and could barely move.
TO Chelia easily outclasses the feats from the Gods of Ishgar in my opinion. She has better attack and speed than all of them. I can't really compare her to Warrod, Wolfheim and Jura. All of them will be blitzed and defeated by Heavenly Gathering of Clouds (including Jura, since this spell seems stronger than Rolling Thunder). The only one who could've a fair chance against TO Chelia is Hyberion, since his magic is pretty hax.
When did I say DF Wendy and TO Chelia have better defense than the Gods of Ishgar? I only said TO Chelia has better attack power than God Serena.
Di Maria is stronger than God Serena.
We know that Chelia and Wendy can't beat Bluenote in Base Form. And Bluenote should be below Current Jura, but let's assume they are the same. Wendy goes DF. Now add in Warrod who should bridge that gap quite evenly (if not too much). Chelia gets TO. Just add Hyberion and they should be equal again. But notice how we still have Wolfheim left so the 4 Wizard Saints > 2 Sky Sisters in durability.
It would be more like this:
TO Chelia > Jura (high diff), Warrod (low diff) & Wolfheim (mid diff)
TO Chelia + DF Wendy > Jura (mid diff), Warrod (low diff), Wolfheim (mid diff) & Hyberion (high diff)
DF Wendy is only a support to bring TO Chelia to victory. TO Chelia is more or less Spriggan tier, the Gods of Ishgar aren't.
In order for Chelia to heal herself, she'll need time and concentration. That will be difficult for her to achieve especially in a mid-battle fight against a strong Spriggan.
You're referring to Base Chelia. Since Third Origin increased Chelia's magic power, her ability to heal should be far better as well.
If she had enough attack power to break though God Serena's defense, then that would work. But from what we've seen, that is really hard to imagine.
God Serena's defense isn't impressive. Chelia would easily break through once she blitzes him.
