RTF is a global modification that replaces all towns in the game.

But wouldn't the Latnik Sword be a good basis?
 
Great Axe also sounds good, and a modified beak on a long handle could work, like a lucerne hammer.

the Latnik sword is suitable, but there is, for example, a steel sword from Skyrim that doesn't differ in structure and also fits, but they won't fit the Warcraft armor visually

That's a pity. I just remember that there is a connection with the skeleton/animation. If you tried to apply the Titan's animations to another creature, you might remember how it swells to enormous sizes. And those that are more or less compatible (Earth Elementals) can pass for their giant version, with such an animation. 🤔

this is all garbage, it distorts the units, even closely related models can suffer from this, for example, Nicholas cannot fully clench his fist in the Latnik animation, the archer fits well with the monk and peasant animations, but his neck stretches - I think this is an acceptable flaw, it's worse with the dwarves - the javelin thrower with the mountain defender animations gets bent fingers, and his eyes sink deep into his head, the skirt is not animated, the rest of the combinations are usually unsuitable

once I saw a unit on the Rakshasa princess model with the Rajah animations, due to the huge number of attached models, I couldn't figure out what the flaws were - an incomprehensible Polish genius X) in another of their models, I saw an archer-monk
