Which faction poses the greatest challenge for the Dwarves?

Dude, Mish-gan, I advise you to choose an education that can save you from the Orc (if only...). If your skills are overflowing, then choose Inga; she will ensure that you get the Energy and Resurrection runes:):):)...and also, if you lack mana for Light or Chaos spells... Even if you choose Ingvar, your defenders won't be as powerful against the "beastly" Warmongers of Tilseck (Ingvar is only strong at the start and in the mid-game, although you can try, but Tilseck has a better chance because the Orcs have insane growth and it's difficult to defeat the Warmongers in the Castle Arena, even with dragons, especially if you only have runes...). Helmar is not a worse hero, but he is more focused on magic, which is inferior to the "beastly" Warmonger squad; he doesn't have an enhanced squad. I'll give you two pieces of advice: 1. Does your opponent choose an education if they are going into the Castle Arena (maybe... but still?)? If not, then confidently choose an education for Helmar or Ingvar, but I would choose Inga for this battle. 2. Try to surprise your opponent instead of leveling up in the usual way... especially with magic... and especially against an Orc. I remember a battle where I was the Dwarf Erling, and mines appeared in the guild. I thought, "Will they level up through summons?" And they did + education + defense, resulting in a level of around 23-26. In the end, I won purely because of the mines and phantoms with a phoenix!
