The best location I could find to do the Bow of Fate V challenge
Requirements
Fire Imbuement
You can unlock Fire Imbuement by going into the Abyss and solve multiple puzzles. The starting point is the Spire of Ringing Truth in the south of Pailune. From there you will unlock Frost and Fire imbuements.

Volcanic Eruption Abyss Core:

You can find it in the waterfall between Hernand and Demeniss, where you have to extract it from the Scorchflame Gloves – or use them.

A solid bow

I just threw Attack and Crit Abyss Cores on it to maximize the Damage – It can be any bow.
Location
Ironwood Forst Bandit Camp
The bandit camp is south of Demeniss and a little hidden in the woods, but it contains multiple “low level” bandits that stand closely together.
