If you are SVD then you should not put any agi man..
This was true in old old old old RO mentality. Then SVD Knights on iRO took some notes from Korean players, who added in 40 total AGI for Pierce spamming or BB spamming. Hell, even Brandish Spear, Spear Boomerang, and Spear Stab increase in effectiveness, as their animations are affected by AGI.
Most smart Lord Knights figured out that a little AGI in their build actually helps a little with even pure Clashing Spiral builds.
It took awhile, but even Rune Knights going pure Dragon Breath figured the same thing out, because virtually all in-game animations are affected by AGI, allowing bypassing skill delays by figuring out the right AGI to get around animations, allowing faster spamming, and even near perfect cast without maxing out Dexterity.
I know there are some people who adhere to this mentality still, but most of them have never experimented with builds, or they'd know better.
mlmf is quite accurate in his assessment.
This is particularly true if you want to actually kill high HP value targets quickly. You don't need a lot. 40 AGI goes a long way.
That said this guy is a bit high for most SVD, and is instead a hybrid build, a bit closer to my own, and while it's effective, the HP pool will definitely suffer a little. SVD in renewal really should be retitled VSD given priority should be to VIT first.
