As you may have known, the combinations for legendary monsters have changed,
And the combinations on this wiki is no longer up to date. So, I decided to help out by posting the new combinations and here they are:
Vadamagma: duchess+skipples Nemestrinus: rhynex+darknubis Rockantium: musu+terracrank Thorder: rabidex+Tartarus Lord of the Atlantis: rasfreesh+ drop elemental Goldfield: erpham+drop elemental Please do not edit! I will add more combinations when I'll learn about them! Note that there is only 10% of chance that you'll get a legendary even with these combinations, so you might have to be patient.
