Regarding KMS scrolls and seeking advice

To quote Fiel's extraction:

030041.level.1.incSTRr 3
030041.level.2.incSTRr 3
030041.level.3.incSTRr 3
030041.level.4.incSTRr 6
030041.level.5.incSTRr 6
030041.level.6.incSTRr 6
030041.level.7.incSTRr 6
030041.level.8.incSTRr 9
030041.level.9.incSTRr 9
030041.level.10.incSTRr 9
030041.level.11.incSTRr 9
030041.level.12.incSTRr 9
030041.level.13.incSTRr 12
030041.level.14.incSTRr 12
030041.level.15.incSTRr 12
030041.level.16.incSTRr 12
030041.level.17.incSTRr 12
030041.level.18.incSTRr 12
030041.level.19.incSTRr 12
030041.level.20.incSTRr 12

This is the +%STR data for Uniques:
level 1~3 -> 0-30 (+3%)
level 4~7 -> 31-70 (+6%)
level 8~12 -> 71-120 (+9%)
level 13~20 -> 121-200 (+12%)
Basically translates to 1st job 3%, 2nd job 6%, 3rd job 9%, 4th job 12%.

I don't think there are any 121+ equips at the moment though so it's just academic. Unlike the Chaos Zakum Helm, the Chaos HTP still requires level 120...
