Yeah I think it goes like this: Hydras gain heads for destroying three buildings or something like that. Walls do count in the vanilla game, but Titans Expansion made it such that their heads no longer increase in number for destroying walls.

That aside, I really can't skip stating that Hydras are easily one of the most annoying, yet not all that powerful, AoM myth units ever.
