Most profitable Loadstone via MF
well, ‘profit’ is misleading here. what you’re doing is turning SP into gold. I wouldn’t exactly call that ‘profit’. In general, core → lodestone conversion is one of the lower returns.
to answer your question:
charged gives about 10s/SP
corrupted gives about 26s/SP
destroyer gives about 29s/SP
molten gives about 51s/SP
onyx gives about 56s/SP
some better returns (1-4g/SP) can be had from promoting refined materials. especially T1→T2. It’s a bit more time consuming, but more rewarding.

Maybe I should promote kitten stuff then. Got over 2k skillpoints to spare
I like this sheet to see if it’s worth it to upgrade materials
