Well, that limits it quite a bit.
Base game without at least Ashes of Malmouth DLC is really different, a lot of items don’t exist, max level is 85 instead of 100, lots of devotions don’t exist, and so on…
No current guide (that I know of) still applies to base game.
I wouldn’t even know where to look for one, as old guides (from before-DLCs-existed) might be very outdated.
If you have at least the AoM DLC, most of those problems disappear, you just can’t play any class with Oathkeeper and can’t use items from Forgotten Gods DLC, most of which can be substituted.
Edit: There is this thread with old pre-DLC build guides, maybe it can help.
