OK before you argue.
I know DVS is stronger regardless.
I was just in a heated argument with this knight-elite Iron-Rust and he was sooo #@#%ING stupid!!! I said that DVS vs WHB do have the same power at basic stock dmg no add dmg (besides the dmg bonus very high on beasts for WHB). And that with max dmg WHB's beast very high becomes USELESS and that DVS pulls through with poison which INCREASES dmg to the sword and keeps the monster from healing. Then he said that poison only stops the monsters from healing AND that poisin dmg would be cancled out because of max attk dmg. WTH are you &$^%ing retarted??? POISION NEVER CANCLES OUT AND INCREASES DMG! can someone please kick some sense into this iron headed idiot...
Please, watch your language. Some of that is kind of pushing it...
Now, to answer your question in my opinion, it doesn't matter what extra damage from poison or beast damage you get, the phantasmal swords hit more often than the spirit wolvers do, so regardless of damage, DVS will have a higher damage output potential than WHB (this even goes for Poison Stratums).
