if i remember correctly, i think you only have 6 extra stat points(instead of 12) if you go 160 int.Crimson armor = 160 INT
Elysium staff = 138 MP
At level 59 that leaves you with only 12 stat points to put elsewhere, presumably in HP. With 50 base health points, plus 12 additional, you'll have 62 points in health. Depending on your items I would guess you'll have around 1500 HP, maybe a bit more if you have good stuff.
You would have good ac, good attack, but lowish HP. Playable, but you'll need a good healer.[/b]
