the items i used on my Wiz were this
1. Pupa shirt or watever with pupa - 700HP and pretty cheap
2. Raydric muffler - much better considering a +7 immune mant is only 2mil ( now i have +7 devi, but this one is better )
3. Rigid guard - gives 400HP for HP boost, forgot the card name
4. Phen clip - for uninterrupted cast (but u can avoid this by going dex gears )
5. Some shoes with SP boost or HP boost ( i have eddga )
6. apple of archer hat - for dex+3 !
7. Dex survivor rod or staff or want with int boost and matk boost
In simple terms of investment for your dex gears, consider upgrading to these
1. Apple of archer - dex + 3 must have
2. Sting gloves * 2 = 15mil together .. or a phen clip and sting glove
3. Stem worm muffler - 3mil if u r lucky
4. Dex rod and rigid guard for beginners gives a 800HP boost together or go for quad dex rod
5. Pupa carded armor is better than rocker armor, unless ur dex comes to multiples of 10 with rocker card
so ur dex at later stage will be like this
99 + 3 - base + stats
+ 4 ( dex rod )
+ 3 ( apple of archer )
+ 5 + 5 ( 2 stings )
+ 5 ( stem worm)
99+20 ( add a rocker armor, u go at 99+21 = 110 dex)
Note : u wont need a phen / harpy card. Just get a blessing or use some dex food and run and cast in prison .. u wont get hit unless u run into some zombies !!
i have tried and use this method and this is far better than the wizard combo ( more HP boost is required. Since u already have a lot of SP Pool )
