The Big 3

You really want a Holy Armor as soon as possible to get White Lily Collar. This item is very important to get to 15 Luck faster to trigger the effect of Mega Clover as soon as possible

There are plenty different weapon versions of that build. Usually it is played with a Hero Longsword. If you're playing with a Spear aswell, a Poison Spear can be very good tempo.
Lightsaber is the 2nd best weapon for burst if you can trigger the effect right away for the bonus damage.

If you can fight enough Heroic Potions for stamina you can take Impractically Large Greatswords. Strongest Version is with 2 of them but you'll need enough Stamina to support it.
