You need to have the Replay client that comes with kRO, not sure if there's a translated version of it yet. Untranslated, it shows up as s patcher window with 1 button, click that and it will patch RE. Afterwards it will open a small client window (havent really messed with it), with some question and 2 buttons, the first one opens a list of Replay files, 2nd one closes the client.
exp.txt in db/re or db/pre-re
Each class type (Baby, 1st, 2nd, 3rd) has a base level entry and a job level entry (with some jobs split further)
Ninja and GS are already 70, so just change:
50,4047:4048
50,4049
to
70,4047:4048
70,4049
Its likely a disguise, apparently the Valkyrie Helm from April Fools Day also did this (but changed you to Randgris), dunno about a stat boost though.
