Best way to farm Zinogre?

[Power]

I got the forest area on the guiding lands to level 2 and he appeared, I captured it and it unlocked it's arena quest. However, I want to farm his full amor plus 2 weapons, so it will take a long time if I need to wait either for he to appear on guiding lands or for his arena quest reset. There's a better way to farm it? Thanks.

Best way are Investigations, so either collect more tracks until you get some, or look for Investigation SOS Flares

Investigations are still the tried and true way of getting endless amounts of monster materials. Collect tracks, jealously covet and guard your own Investigations, while trying to join everyone elses etc, until you get what you need!

Investigation by collecting tracks or breaking his part.

Lure him out into guiding land. You can get lure by completing the guiding land Fanged Wyvern analysis (RNG based). Breaking parts or capturing other Fanged Wyvern monster in guiding land can progress the analysis.

I see. Thanks for the help. Also, sorry for the dumb question, I just can't remember, can you get investigations during arena quests or only during quests/expeditions? Thanks again.
