its not, its impossible to get gg claws and crescent moon is the way to play until u find gg claws, im gonna try with horazon boots and minmax to get some more mana 1st and then decide if its good enough, will post results after testing this out
I mean you can always use a 40ias substitute in the mean time. Its either crescent moon as you suggested or that. But claw block is very strong since it can block anything including spells.
