- A reference guide and manual in Russian for Heroes 3.

It's easy to check. Equip Thorgrim with artifacts that grant resistance and attack the dragonflies. I've never seen them resist the ability, whether it's the dragonflies' weakness, the horses' blindness, or paralysis, etc.

And today, I took the time to create a situation in the editor and saw it. Thorgrim, level 59, with artifacts that grant resistance, is completely immune to the weakness of the snakes. But the innate "remove any positive spell" ability works. Moreover, there was no graphical effect of resistance. It just didn't trigger. It was as if they weren't dragonflies, but some spearmen were attacking.

Of course, if he resists the dispel, he will also resist the weakness.

I was wrong.
