The map is good, but as a mapmaker, I can say:
If you play it online, there is a slight advantage for the red player. Specifically, if you remove the artifacts on the road, the hired hero can reach the oasis on the first turn, but the blue player cannot because he is a few steps short. I'm just pointing this out for the future. If you plan to use this map for online battles, don't forget to fix this unfairness.)
You can reach it by using a vial of endurance if you really need to. However, it's not available in all castles. BUT, it's possible that the other player has other advantages: for example, if I'm not mistaken, the blue player starts with one more altar than the red player.
