Questions regarding summonable Legend Cards

Hi, as you have probably guessed, I’m a sorcerer, I recently obtained the legendary version of Froster Lord and started summoning it as a consequence.
Can I expect any difference in damage in comparison to its normal counterpart?
If it’s the case of how much and what would be the easiest way to level it up?
Thank you in advance.
PS: for now I don’t see much of a difference in damage between the lv1 legend card, a lv1 normal counterpart and even a lv10 normal counterpart, so maybe damage doesn’t depend on the number of stars and both normal and legendary version do the same damage…
