Could you provide the quote where she says she still using ronova amp during the battle?
Lord of the Night stated:
"A key part of Mavuika's plan is using the six heroes to release the power Xbalanque obtained from the Ruler of Death"
"The Ruler of Death's power will allow Mavuika to triumph over the Abyss. But, she must offer her own life in the process"
I already talk about this before, the only way Mavuika to defeat Gosoythoth is either using Ronova's Power or Gnosis Power and we know she chose Ronova's power option.
From this Statement from Lord of the Night, it is clear that Mavuika will use Ronova's Power until she manage to defeat Gosoythoth.
"A key part of Mavuika's plan is using the six heroes to release the power Xbalanque obtained from the Ruler of Death"
so the Key for Mavuika to released Ronova's power is using the 6 heroes of Natlan.
And Theres 2 Moments where Mavuika released Ronova's power.
1. The first one is this cutscene:
2. the second one is this moment when we fighting Gosoythoth, the Lord of the Night helped Traveler and Mavuika by brought 6 totems of obsidian that represents 6 heroes of natlan so they (Mavuika and Traveler) can release Ronova's power once again:
Again for the last time, MAVUIKA CANNOT BEAT GOSOYTHOTH WITHOUT HIGHER POWER.
People who saying Mavuika beat Gosoythoth with just her own Power/Authority is straight up stupid while the lore literally said Mavuika will use Ronova's power to save Natlan. Like bruh..
If she's strong enough to beat Gosoythoth with just her own power, without any higher power involves, then why is Gosoythoth isn't getting killed by the Previous Pyro Archons? Why don't Mavuika just killed Gosoythoth 500 years ago?
