When playing as a Warrior, you need to decide whether to invest in Wisdom or not... And all those weak builds are just funny!!! I would never take Wisdom hoping for a Guild of Mages level 3! If you're going to build Guilds, don't do it in your home Castle, but in a Castle where you have a 5th-level Guild, then you can level up Wisdom. And if you can find books or a speaker's hat on the map, I wouldn't take Wisdom at all. This applies to XL difficulty, but if the map is small, take one magic skill (you always get one at level 4), and the rest should be combat skills, and go for it!!! If you need higher-level magic, you can always take Wisdom later, at level 6, 12, or 18!
