Addled Frog

The Addled Frog is a unique and optional fight located in the Sunlit Wetlands. Using Speak with Animals will reveal the frog seems to be in a state of painful madness, somehow caused by the corruptive magic of Auntie Ethel.

If pestered for too long, the frog will become hostile and, despite appearances, prove to be very deadly. However, if the hag is dead or forced out of the area, the frog will regain its sanity and lead the party to a hidden stash of items X: 7 Y: 294 as a reward.

Tactics

Despite appearances the Addled Frog has an unusually high Armour Class thanks to its Mucus ability and having Mirror Image when the fight begins. While it may have one attack, it's quite powerful and its AoE can hit multiple party members if they are grouped up. It will also use Jump quite often to create distance. Also, be wary of the first ranged attack or spell that hits it, since it will be reflected.

While the Frog can prove to be quite deadly, it has relatively few Hit Points, and so it is vulnerable to a well-prepared melee fighter or a Sleep spell. If its Mucus trait is gone, a burst or two of Magic Missile will also likely kill it. However, considering the Frog only gives one experience and drops nothing, it's not worth picking a fight with.

Footnotes

Reflective Mucus will counter all missiles fired from Magic Missile spell.
