What could DRK have learned from FFXI?

[kazzel120]

1. You pair it with a Ragnarok accessory and you don't take damage from darkness in 10-2. But typical game play style requires you do take the damage.
2. For tactics you have abyssal blade and Unholy sacrifice. You also have Vehemence which increases your physical damage and lowers your defense.

So the tactics remake. Because gafgarion and cid never once took damage from their sword skills. In the original.

And i said if you count x-2 as one of the versions where DRK took their own hp to deal damage. All other drk renditions never did any of that. Except for original jp hard mode iv and even then darkness was such a weak skill cecils normal attacks did more.
