Yeah, it is very good module even if it is 3.0. You just need edit out the common caster stragedy to use haste spell or haste potion able cast two spells (as in 3.0 edition haste gave extra action). I changed spell lists little with some cheese from splat books as the players also cheesed up but they are using bladed gauntlet which is 3.0 edition weapon from sword and fist (a 17-20 crit weapon, but it may be wrong as actual crit is 14 than 13 now that I think about it but it still cheesy. May nerf it to be more around level of kukri and then it is 15-20 to be more fair).
