What is your opinion on the possibility of introducing a third tier of maps and a new faction into the game?

Okay. The hero's specialization will be the "Water Gate" skill – something similar to the gates in the Inferno Castle in "Heroes 3," but the hero will return to the castle for a fee. I'll post more details in the evening.

Some things have been fixed. The requirements for reaching certain levels to enter (or exit) the water (from under the water) have been removed. Instead, two artifacts are introduced: "Sphere of Water and Air" and "Sphere of Earth and Air." The "School of Underwater Swimming" is removed.
