i would do mp eater, then invincible, then teleport, then bless, then 10 points into something random,
thats just my opinion since bless does almost nothing except 20 accuracy, and that only affects warriors and thiefs. if ur partying, then u should do that before teleport. Im think that teleport will be much btr if u are going to fight alone around lvl 50s.
if u really want holy arrow, then take away bless, as u should keep all the other skills.
