...when u hit lvl 10 u become the next job automaticaly also when u evolver ur lvl goes bak to 1 and all ur stats are still the same as before and then u get new skills and are able to use ur old spells as well as learn new ones.
You might have a problem with that. (And its not following how Maple actually works.) When you level and upgrade your character in WC3, then you select the abilites you want to upgrade thats all good. But when you downlevel a hero, the abilities become unusable...they get greyed out. I dont know if this is because of techtree requirements or level requirements, but like I said...you might have some trouble with putting your level back to 1 and being able to use the abilities.
You might like to look into the techtree requirements or other requirements of an upgraded spell and see if you can get it to not be based on Hero Level.
