Genius Golem

What's the trick here? I gather you have to hit it with all six elements to damage it. But you're limited to five party members. So even if you have five different elemental attacks in your lineup, where do you get the sixth?

[Acaykath]

Use the steles to get dual element magic, or just hit it hard enough that it dies despite the resistance. I one-shot it with physical damage.

[luxtizer]

What attack value did you need to do that? I'm wondering if it'll be quicker to grind attack or grind the inspiration I'll need for the dual magics.

[Acaykath]

No idea what my attack value was at the time, though I have 90 million status ups and I did not need to switch to a stat-boosting party.

[Powen Yao]

Characters like Iari and Norn can cast magic with any element and dual-element magic.

[Alkrios]

Another unfriendly option is to change a skill on a character in the middle of the fight

[Synthar]

there are monsters with all the elemental skills, copied from discord, not my work:

Boss strategy
All magic city dungeons you get a 1000 physical attack divider so its better to use magic
To disable the boss`s magic barrier you need to hit it with fire,water,earth,wind,ice,thunder attribute attacks
Skills for these elements are available in magic city, but its doable without any of the skills using default attacks

Specifically
Silver scale dragon (wind,earth)
Red slime (water,fire)
White wolf (ice)
Yellow slime (thunder)
(main damage dealer in slot 5 to kill)

i just brute forced it with physical attack high enough to finnish ending 6 with a few ten thousand in glutony

Just use physical attacks. It's one of the easier bosses, even for a magic build. I managed to one hit it with Love Hug with physical formation. I mentioned this in my Achievement Guide as well.
