Losing sp while boosting up zerk with combat order Hi, i recently reached 4th job as a Drk. I was training at lion heart castle in a party of 6 with a paladin who buffed the party with combat order. My berserk level was at 10 (+2) from combat order, i had sp from the recent level up so i started putting it into berserk without using berserk 20 yet. ( I hadn't found the skill book at the time ) So the berserk level was at 12 (+2). When combat order wore off, the berserk level reverted back to 10. I was nervous at this point if i had loss the sp or not. I asked my guildies and alliances but they did not know what to do either. I searched fm for berserk 20, used it and failed. I purchased a second book, and this time it worked. Berserk mastery
