Ones Fallen Into the Abyss Walkthrough

	Quest Walkthrough
1	Once you reach Trailblaze Level 14, head back to Jarilo-VI and make your way to the entrance of the Great Mine at the southern part of Boulder Town.
2	Watch the cutscene that triggers between Natasha, Seele, and your team once you enter the Great Mine.
3	When the cutscene ends, the Relics game feature will unlock. Equip the two indicated Relics for your character to proceed with the mission.
4	Head up the ramp and make your way to the large bridge leading deeper into the mines.
5	Once on the bridge, speak to Peak (sleeping man) and Elaine. They will direct you towards Oleg and his Wildfire associates. Speaking to Elaine will also allow you to obtain Findie, a robot you'll need later in the mission.
6	Make your way across the bridge and head deeper into the mines. Defeat any enemies blocking your way.
7	When you reach the derailed Mine Cart, a new game mechanic called the Home-Use Object Finder will be introduced. Use Findie to locate the mine cart parts hidden nearby.
8	Head into the yellow circle indicated on your map. Use Findie within this area to locate the Mine Cart Pin near some rocks.
9	Move to the next yellow circle. Use Findie within this area to locate the Mine Cart Wheelset near the box of Geomarrow (beside the Calyx dungeon).
10	Once both parts are secure, return to the mine cart to fix it. Push it forwards to clear the way into the mines.
11	Engage the Automaton Direwolf in combat and defeat it to progress the mission.
12	Continue deeper into the mines and deal with any enemies along the way. Once you reach the lower levels, a cutscene will play out showing both Clara and Svarog. Warning: Once the cutscene ends, a boss fight will trigger. Make sure you have the proper team to deal with the Automaton Grizzly summoned by Svarog.
13	Defeat the summoned Automaton Grizzly.
14	Watch the cutscene between your team, Seele, Bronya, and Oleg. Once it ends, the next quest, A Sunset Rendezvous, will trigger.

Deal with the Summoned Automaton Spiders to Trigger Explosions

Defeating the Automaton Spiders summoned by the Automaton Grizzly will trigger an effect called Chains of Destruction. Prioritize taking them out so that they self-destruct and deal damage to the Automaton Grizzly at the same time. Spiders will be weak to Lightning and Wind attacks.
