Heres what my blade has.
Bloody + 8 - DEX x 20 Awakes (One Handed)
Bloody + 8 - STR, STA x 10 Awakes (One Handed)
Full Armor set i get around
60 DEX
40 STR
50 STA
20 INT
ATK Speed + 20%
Crit Chance + 10%
And my build is pure STR. You see when you get to LVL 65+ You get more knockback on the mobs then you think. You can use this to your advantage. If you continuesly attack them and make then knockback then you'll take around 3k Damage if they hit you (Whitch is VERY Un-Likely because there flying everywhere and can't stand up) Awake your Swords to DEX for Attack Speed + Crits.
I do around 20k Damage + I only take around 5k Damage from mobs 5- my LVL. I'm now a LVL 131 L Slayer. When you get to the strength break you'll do x2 your damage. With all you buffs activated you'll do a HUGE amount of damage.
I would also reccomend getting 9999 HotDkugDkug in your F2 Slot and using it whenever you get hit.
By the time your LVL is 121 You'll get around 15k HP. Not enough? Go to Is in flaris and buy some HP Increase items. ( i got my HP too 25.2k from there)
