I'm about to leave for vacation, so I won't be able to work on any more spells. Sorry to the people who I wasn't able to help in time. Anyway, I guess this spell thread is now considered closed.
Finished Areana's spell.

You can achieve that by going to the second condition of the second trigger and changing the 60 to 15 x level of Ability.
So the ability is supposed to just change the appearance of the unit right? The attack damage, armor, abilities, and if their Heroes, hero attributes and learnable abilities should all remain the same?
Offtopic: Third page! For me anyway.
All possible solutions I've thought of to make that ability either don't work or are impractical. Using morphing abilities is impractical because you would need a morph ability for every unit type. So the only option would be replacing units. Replacing units wouldn't work if the casting unit...
I am 100% sure that you can passive abilities in spellbooks and they still get their effects. Also, for the third myth, you should include that you can change the Order ID of Channel, Spellbook, and Charge Gold and Lumber.
