I use 3 "Goldenring Cards" and 1 "Turtle General Card" .
(That gives the most damage on players because of the order in how the cards are read.)
Olso for players who have High Vit. You can use 2 "Goldenring Cards" 1 "Turtle General card" and 1 "Thanatos Card"
(That combo will obliterate Sacrafice Palladins or any other class that uses high Vit)
Well that is what I use on Players.
But for MvP's Just use 4 "Abysmal Knight Cards" and hit the MvP with its Weak Element.
(You can research MvP's Items and Monsters here at Ratemyserver.net)
