NHF – new heroes for Heroes V 3.1.

Of course, it's not necessary to include unbalanced units in the mod (Markel, Tolgar). But extra heroes with identical skills and icons wouldn't hurt. By the way, Guard doesn't have a scripted name, which could cause an error.

In my opinion, I disagree about having identical skills.
You could simply give new skills to those campaign heroes that have identical ones.... :)
Guard is in UVH with his own icon. You can take it from there too.

Here is a possible skill (clarification): All enemy heroes within one path of the hero are entangled in roots until our hero leaves or kills them. The ability only works on heroes whose level is lower than our hero.

Zeheer is almost a cheater; he needs to be weakened!
Maahir is a copycat; throw him out.
Syrus is a copycat; throw him out.
Gotai - why not, let him stay!
Kujin - will there be many demons? Crematorium awaits!
Kun'yak - copycat, for the Chinese to eat!
Kurak - copycat, appetizer for Kun'yak.
Agrail - the skill is similar to Wing's. Should we change it? Or do we even need such a transgender mutant....
Biara - she's quite a beast. Copycat, for recycling.
Wayer - didn't even get his own face, let alone a skill. Into the lava!
Lord - too awesome to be among these commoners, and also has that kind of skill.
Guard - join Wayer in a look-alike contest. (Although he can be reworked; a new icon already exists)
Orlando - quite a wizard, if only he didn't have that skill, which is the most popular among demons; then it would be good.
Erazial - well, here we go again "Ukraine Has Talent". Clones attack!
Alaron - we can give him a pass; he deserves it, unusual ears.
Tieru - he's a good guy, but they probably sat next to each other in school with Wingael and copied from each other. Biara was right about you, goodbye.
Faidaen - a real beast, an elf. With proper use of the skill, attacking turns into sitting around with chips and beer. Let him roam the forest.
Agbet - yes, dark elves have one clan – one skill! How is this possible? To the sacrificial altar! Irbeth is nervous
Ilayya - normal face, but rotten inside. Irbeth is very offended!
Railag - there are actually 2 different skills here. Lowering enemy initiative is still acceptable, but giving your own magic kick is too much.
Ranlit - well, this is a dream for a football fan who likes to sit in front of the TV somewhere in the village. And the skill is frankly stolen from Sorgal.
Tralsai - Irbeth is just furious!
Shadia - even Matrix would be impressed; let this werewolf join the mod.
Sigrif - Irbeth seems like she will commit suicide! And Sinithar will add...
Arantir - sacrificed for the sake of good intentions. In principle, Sareth did the same thing.
Giovanni - oh, he should marry Lucretia, but not join the mod!
Markel - terrible beast! Lock him up, tear him apart, burn him, bury him in concrete!
Nicholas - Vladik is indignant.
Ornella - we'll have to destroy another grandmother! Down with matriarchy!
Alaric - his skill, as well as himself, *is not very good*!
Andreas - Vitia, you were cloned; it's time to exterminate!
Benedict - Rutger has already left!
Bertrand - don't tell Laszlo about him. It's a pity for the old man.
Valeria - her sword is something else! But Axel will punish the girl.
Gabriel - fly faster, before Iris cuts off your wings!
Godric - what a guy! We'll take him into our ranks.
Duncan - a hero from Scottish fairy tales! Rutger will have a hard time!
Isabelle - a successful blessing, but do people really need such a skill? Maybe redskins?
Laszlo - this clone is identical down to the last DNA element. Phantom or Fatush...
Lorenzo - Vitia, Vitia, you squandered all your wealth on the reds....
Nicholas - what a guy! Handsome and generally a good person! I would give my life for him!
Orlando - what does Lord of the Rings have to do with it? And griffins too?
Ornella - Rutger finally found a woman, but Giovanni turned out to be more decisive!
Frida - oh yes. Divine freak and diet will allow us to accept her into the mod.
Jir - experiments in crossbreeding were carried out successfully, but the product must be destroyed!
Glen - second specimen. Subject to mummification and burial.
Wulfsten - only his ginger beard makes him worthy of joining the mod.
King Tolgar - truly a king! But he didn't have enough brains. Go join the cheaters and eat oats!
Rolf - flatterer and fool. Tolgar will miss him, so send him there too.
Hanvul - if Erlig knew, he wouldn't have gotten involved. But an owl saves – Hanvula goes into their own castle!
