Yesterday, I made an Update to Port Traventor.
Namely, I've added 4 Battle Towers, where you fight tournament battles against increasingly stronger waves of enemies. Each tower has a total of 5 battles that must be completed in a row in order to win the special price. In any case, you can get a whole bunch of tools in each tower. However, even though this is considered optional content, those towers neatly enhance gameplay.
I also made a few more changes. Magic skills now have a smart new effect (darkened screen while casting spells) and some enemies in the late game have been adjusted in difficulty as well.
You're still into Port Traventor? Well, you'll like this Update! Have fun.
