NHF – new heroes for Heroes V 3.1.

We could consider scaling it based on level.
I wouldn't want to nerf the special ability too much, as many people like it.
Is 1% per 2 levels a good balance?

There are many reasons to like it... We could create a hero with an even more powerful special ability – people would love that too.
In general, Leto's "Poisoner" specialization has some similarities, but at least its effectiveness depends on the hero's level, and the soldiers don't die instantly, but with a delay (meaning you can have time to remove the plague) – for this kind of idea (an idea for a pre-battle phase aimed at partially weakening the army), Leto's implementation is the most appropriate.
But by the way, there's something I'd like to discuss – I really don't like the fact that the specializations of some heroes are completely useless when fighting certain factions. Let's consider Dyra and Leto – if our enemy is undead, their special abilities are completely ineffective. Maybe we can come up with something for that? I would like every hero to be able to prove themselves in some way in any situation (Dyra and Leto can only prove themselves when fighting undead by clearing out neutral creatures – that's a shame)
