Even if it was true (which it isn't), you probably don't want a general to spawn while you're solo and underleveled.One more tip in doing dolmen when you close one of the 4 pinion that spawn with the dolmen you regenerate to 100% of your health/stamina/magicka and I think you also get a buff to your damage done. Do not be afraid to make use of these. Ignore anyone who tells you that leaving all 4 open until all mobs are defeated gives you a better chance at a named general, it is pure superstition, and has been refuted on ESOlive.
