In preparation for an upcoming online campaign, I was pregenerating a character and charting my planned advancement. I created a Half-Orc Monk (Lawful Evil). I loaded him with XP and began levelling to add the Blackguard prestige class. The requirements listed online and in-game are 1) Any Evil (check), 2) Hide 5 (Lvl2), 3) Cleave (got it), and 4) Attack +6 (Lvl8), but I was never able to level in Blackguard even up to the SoU limit of Lvl20. Assassin and some other classes opened up, but not my choice. Are there some other requirements, or am I missing something?
