NHF – new heroes for Heroes V 3.1.

If that's the case, then my option is valid. Because the chance of a tenfold repetition of an existing spell is too small. Although I would hedge my bets up to 100 or 1000 regenerations, depending on performance, just to minimize the absurd case where, after 6 misses, there is NO automatic hit due to repetitions. Since such a situation is perceived as a bug (if the player knows about the automatic hit after 6 misses), its chance must be minimized.
