Oh ye, attribute challenges from Median 2008 were quirky. The highest one (AC 1000) required you to have 1000 stat points unspent out of total 1205 (1190 from levels + 15 from quests). You got 10 stats per level and there were no signets, max level was 120. And it required to beat one of the most difficult uberquests at the time.
But even harder challenge was the 'level challenge from hell' which was to complete Tran Athulua on normal... on level 10. Yeah, level 10 xD
It was pretty challenging to even get there at level 10, let alone complete it. You can hit level 10 by completing Den of Evil on /players 8
Needless to say, only select few builds were able to complete it. And once you did, you just duped the hell of this charm to any further characters you made (M2008 was primarily singleplayer so yeh). The challenge was far too ridiculous to complete on every new character. So it was eventually axed and set to level 50 where it remains to this day.
I like this patch, maybe i'll play it. I skipped few patches in favour of POE, but now Im pretty bored with POE.
