The black magic spells "Sleepga" and "Sleepga II" will be released.
Yay. Same for Stun and Flash.
I'm going to have to sift through to find some of the updates I was actually involved in the game enough to remember, such as the introduction of Dynamis, light skillchains, and the 3 hour king window (rather than fixed repop timer).
EDIT: And I just saw some updates I forgot about, like Meikyo Shisui giving TP, Astral Flow being increased to 3 min, addition of WSNMs, etc.
I bet there's more update logs, just on the JP version of the site, since the NA version of the POL site seems to only cover up to NA release.
