a clean Psycho Wand probably goes for 10-15 PDs; a Hylian shield goes for like 15DTs (not sure); Centurion Techniques are like 5-3PDs; V801 Is like 3PDs (or given If asked nicely? :'D) and Glide Divine v00 Is like... 10PDs or less?
Missing stuff? Probably a neutron skin (additional 250 MST + 100% Resta range boost. Also has decent EDK, ELT and... Light resistance), a samurai armor (Ra tech boost by 20% + 50 LCK), or a Mother Garb+ (random 50% Grants boost [I think..] and 50% TP reduction); these are the recommended armors for nuking newmen.
Between the Weapons with boosting abilities there are Quasar Staff (60% Rafoie; 45% Gifoie[I think..] and 120% Barta); Sacred Bow [Hell Special & 50% Grants Boost]
