I know every area has its hidden chest, that usually has some really good rare and high level gear.

I know of the bush in Garrote Gorge, and the Tree in ravenshore.

where are the other hidden chest located?

hold on a minute, bush in garrot gorge and tree in ravenshore? :O This is news to me, can you please give the exact locations?

Some people claim that it ruins all the fun but for me... well, clicking on every single plant is not what I like most in Might and Magic series. Check this out!

yeah, Follow the River in Ravenshore Upstream until you get to the little bridge (near the Centaurs). If looking up river at the bridge, the first tree on the left shore bank after the bridge is actually a chest, opening it gives many good items, gold, and usually an Artifact.

In Garrot Gorge there is a bush that serves the same Purpose. if looking at the castle from the village, its one of the bush/flowers on the hill directly to your left.

I owned this game on Disc back in the early 2000s, and used to utlize these all the time.

Aparently there is supposed to be one of these hidden chests in every area, but these were the only two i knew the exact location
