Aion's endgame and you'll quickly realize that everything revolves around Abyss Points (AP). Hitting 55 is really the tip of the iceberg when it comes to PvE progression and the ability to be competitive in PvP, as you'll need plenty of pricey gear and stigmas to stand a chance. AP is so important, in fact, that even PvE mobs in the Abyss and Inggison dole it out.
Unfortunately for Daevas everywhere, the AP gods are undeniably stingy. Acquiring a full set of 55 armor, jewelry, and the weapon of your choice literally takes months (or even years) depending on how much AP you manage to farm on a daily basis. NCsoft is temporarily addressing this problem with a new in-game event dubbed For War and Glory. The event's double AP bonuses (and halved AP losses) kick off today and will run through the server reset on March 30th.
NCsoft is also tweaking the game's rifting mechanic yet again, and defensive buffs in Heiron and Beluslan will be removed until March 23rd (buffs in Eltnen and Morheim remain). Both events are part of the larger Spring 2011 Reactivation Celebration, which runs from March 24th to March 31st and welcomes back Daevas to "train for the greatest battle this planet has seen yet."
