Slayer is superior to Trickster in my opinion. I used Replica Oro's Sacrifice and then switched to Banishing Blade + Replica Farrul's. Banishing Blade let's us ignore ele resistances thanks to easy crit cap with swords.

In both cases the target is to use Arn's Anguish for 27% Chance Triple Damage :)

Defense wise, you layer Armour / Evasion with Fortifity + 10% reduced dmg from Slayer (30% reduced in total) and overleech. It is not immortal but tanky enough for softcore
