Question Request for list of files I'd need to modify to exceed the 200 spell/skill limit

I know this has been done successfully a few times. If you've done it in your mud could you post of list of the files that had to be modified in order to increase this limit.

It depends a bit. The 200 reserved skills/spells are divided in 130 spells, and 70 skills.
Expanding the skills-list is as simple as upping the MAX_SKILLS number (as long as you use ascii pfiles, but most people do).
Expanding the spells-list is somewhat harder. The skill numbers match messages in lib/misc/messages. So of you wish to move the skills, remember to move change the message numbers as well. Also, changing MAX_SPELLS means doing something about the existing player and object files (scrolls/staves).

#define MAX_SKILLS 200
Is both in src/util/plrtoascii.c
And in structs.h

And Yea increasing max spells you need to change all the Numbers on the skills in messages, Or else your skills gets the wrong messages.
