Decided to replay the map from version 1.0. I decided to explore the sea more and noticed something unpleasant: on one island, there are archmages with water elementals, guarding nothing. I hope this has been fixed in the new version. Otherwise, the playthrough is not much different from the first one, except that I took "Elemental Equilibrium" against Hangvulich, which helped a lot.
Thank you for the feedback. I know that there was a flaw there in that version; now there is a sphinx.
