Dual Blade Guide (Chaos, Big Bang, and Pre-Big Bang)

Level 1 Bloody Storm has gigantic range and the delay is offset by the spam delay for both skills, which I believe is the same, or similar. You can't actually DPS with Slash Storm or Bloody Storm since it moves you, and has horrible spam delay. The point I was making earlier was under the assumption the delays were noticeable and turning and reattacking was efficient. The delays actually aren't very significant in the style Dual Blade plays. Your goal is to XHKO monsters, and having more damage from Bloody Storm allows this. If say you already OHKO with Slash Storm, then yes, hold off adding points into Bloody Storm until you have 4 or 8 saved up to hit 7/8 monsters. Flying Assaulter + Bloody Storm does more damage than with Tornado Spin, so that chain can lead to OHKO more easily, though Mirror Image + Tornado Spin would be a bigger actual damage increase than immediate Bloody Storm. Bloody Storm is only 10 points though.

Chains of Hell is a terrible skill and completely useless without Advanced Dark Sight maxed.
