How to change a hero's class and secondaries for ever? HoMM3

[ExalyThor]

Mephala is my favorite hero. But how can I change her class and secondary abilities permanently? I generated a bunch of maps and swapped leadership with necromancy manually. Can I do that permanently? I like playing her with necropolis a lot.

This question is somewhat going against the design. You should pick your favourite necro hero,edit him and gave him Mephala's portrait.

In editor you can change primary and secondary skills as you wish but you cannot change class - instead you need to choose different hero, which has required class.

You probably can edit game files, if this is where you are aiming. But it's not recommended. Also you can create your own script in ERA or WoG.

I need Mephala, Neela or Tazar. Armorer specialists.

This is your only way.

Of course you may also satisfy yourself just with Mephala with Necromancy, but you will need to place it on all your maps. Either as main hero, or copy paste packed in prison.
