Titan Quest Anniversary Edition: New secret locations

Of everything exists 3 new “secret” caves in Greece, Egypt and Tartar (4 act). And you can only go through them at a certain level of difficulty.. In Greek you can only get on the norm, to the Egyptian – on the epic, and in tartar – to the legends. Each new location has retextured monsters with new skills, according to the act, in which she is. It's something like tartare in Gadir. Having reached a certain stage, you will be offered to either pick up the prize, either continue and fight the final boss.
To open the gates to each of the caves, need to have 3 the Chaos key (yellow, pink and blue). I will notice, that the keys are also tied to the difficulty level. In other words, if you try to apply the key obtained, for example, normal to Egyptian “danju”, which is only available on the epic, you won't get anything. Keys can be knocked out of all Telchines (including Atlantis), Typhon, Aida, Surta and Suns. They can also be found in orbs in Gelos. However, the chance of dropping them is small.. Therefore, it is easier to get them on mods., maxing bosses (such as Xmax, M4ssBoss3s).

so, first dungeon. Located in Greece near Delphi, behind the waterfall of Chrizeos (the rift of Chaos).
It is only available on normal difficulty. (on epic and legend blocked). To get there you need to have three keys of Chaos, mined exactly on the norm.

A Few Tips.
Before, how to go to any of the above locations, be sure to buy more healing and energy potions. The portal stone does not work there.
Carefully examine the walls, there might be secret passages.
With a weak charm, it’s better not to meddle there. Monsters are very strong, full of different traps (shooting statues in the walls and so on.).
