So I've been using a set of 4 skeletons to sail my little boat across the seas. The skeletons were raised using the Teifling's trait that can be rolled which allows the Teifling to create skeletons as if using the Animate Dead spell. I have read that I can control no more than 4HD skeletons at any given time. My issue is what I can do with these skeletons, the fine print says, "The undead can be made to follow you, or they can be made to remain in an area and attack any creature (or just a specific kind of creature) entering the place." however the fine text for a lesser leveled spell of similar properties--Animate Skeleton--states, "The skeleton can follow the caster and obey the caster’s commands or can remain in an area and attack any creature (or just a specific type of creature) entering the place." and my DM is taking the fine print to heart. What I don't understand is why a lower tier spell provides better control over undead than a higher tier spell, and why I cannot just command the undead to do mundane tasks. Obviously I will go with what the DM tells me, thought I'd like some insight into this or at least some explanation as to why I can't do this.
