In my opinion, it’s very simple – you take him and beat Glathran!
He is no better or worse than any other hero…
Better... not much, but still better! The main strength of the Necromancers are skeletons... And if a hero allows this strength to become even more formidable... Skeletons sweep away everything in their path... They are stronger and faster under Garlthan's command... And I don't think I need to explain how important speed is in Heroes....

Skeletons that do not yield in skills to level 6???:confused: To be on par with level 6, they need about 10 defense and 10 attack... This is possible at level 37 (1775477 experience): +8 defense, +10 attack. But few people will develop to such a level. I have already described the improvement of skeletons when leveling up Galtran here. Maybe my version is old? Check yours.
