What "Alternate random enemy selection" setting does?

[d999]

Can I get more high level mobs when "Alternate random enemy selection" setting turns on?

Alternate Random Enemy Selection: Uses a different seed to generate enemies in dungeons.

Different enemies will appear at spawn points, but they'll use the same generation tables. Where you might have met a Sorceror, you'll meet a harpy, and where you met a harpy you'll find a Sorceror. Levels aren't changed, only places and frequency. It's just a different seed to do the same thing.
