This is a walkthrough for the Archon Quest “The Omnipresent God” which is the eighth quest in Chapter 2: Act 3: Omnipresence Over Mortals. Here, you’ll find a complete walkthrough for the entire quest.
Before the Raiden Shogun’s martial might, you sense that initiating Yae Miko’s plan may not be as easy as you thought. It might be best to leave Tenshukaku and make further plans from there…
Defeat the Electro Archon
After witnessing the Raiden Shogun slaying Signora, she lets you leave alive for your victory. Once outside the Traveler feels strange, but listen to Paimon whilst you slowly make your way downstairs. Eventually you’ll bump into the Resistance and another battle against the Raiden Shogun begins. Your first objective in this battle is to keep dodging Ei’s attacks whilst slowly taking off 20-25% of her health which will lead into a cutscene.
You’ll want to keep a large gap between you and the Raiden Shogun, so you have a lot of room to get out of the way of her attacks, then as she stops momentarily to get her stamina back you’ll want to go in and use you’re most powerful attacks, such as any Elemental Bursts if they are available. Throughout the battle she’ll spin her spear in front of her which will lead into a large shockwave around herself. She can also lift her arms up and perform a shockwave in front of her, so be ready to dodge to the side. As the battle progresses she’ll summon three electro orbs around the arena which you’ll need to quickly destroy one of them to avoid a large AoE attack.
Once you’ve successfully dealt enough damage to the Raiden Shogun, the arena will change and your attacks will be blocked, so keep to the outer edge of the battlefield and keep sprinting around in a loop. However you’ll need to be ready to dash away from her when she teleports towards you to avoid any attacks. After the cutscene has come to close, you can now do proper damage to Ei. She only has one additional attack in the second phase which involves her summoning Electro Rings around the arena, so stay in the center until an AoE appears, then go out to the edge until the center explodes and return.
