Which is stronger – a titan or a black dragon?

who will win, the sorceress or the golem...

If it's a one-on-one battle, no unit from level 1-3 can defeat a golem due to its regeneration... the exception is if Grand Elves manage to finish it off with a direct attack using morale, but even then it's not certain, as the damage might not be enough... and in most cases, they won't even finish it off.
