For a stress-free run you'll also want to have the best title buff (Chaotic Ruler) and double feast (NC+Unity) for this. I usually do this after finishing Solo Raid to make full use of all these buffs.

In summary, all you have to do is to get to the platform way ahead of the NPCs, plant as many Net Traps as you can, start stalling once they arrive until the Last Boss spawns, and kill it fast before the main NPC gets killed.
Tips for Spirit God
- Take a Hwarang.
Hwarang can deal great damage, buff ranged mercs within 5x5 with him at center, and can turn Cata into a decent damage dealer. And you'll need all the multi-hitting damagers you can get once the gates start spawning.
- Bring mob count to 0 before setting up traps.
Once you reach the platform, go through the north stairs and kill all remaining mobs while moving clockwise. Start setting up traps 2 turns after the NPCs cross the bridge. Traps disappear after 10 turns so you'll want to set them up as close to when mobs start spawning as possible.
- Start stalling after the cutscene where the NPCs reach the platform.
This is the part where the NPCs position themselves and start some sort of summoning ritual. From there you it will take a little over 5 minutes for the Boss to spawn. Skipping turns would only summon more mobs so stall all you can and minimize turns.
Letting the timer run to 0 prolongs your turn even more. You can still move a few seconds after timer hits 0.
- Prepare to meet the Last Boss at the South after the 2nd wave of spawns.
With perfectly maxed stalling, you'll only have to deal with 2 waves of spawns. After the 2nd wave, head to the South stairs and prepare to spike the Last Boss.
