Boss Class Ideas

[Sadbackstory.exe]

So my DM is letting us each have a mini campaign we can make ourselves,and since I am new to this, I was wondering if I could get some help with building a boss. I was thinking that I should have a boss with a Dex based AC so that they can do better against the touch spells and guns of my group. Anyone have any suggestions?

Any idea of level? Does the boss get mooks, do they have a base, dungeon or lair which they can prepare?

Boss don't really work unless you are adding mythic tiers to them, to help them make up for the difference in the numbers of actions. Usually the best way to do it, is to have him a slightly lower level with henchmen/minions to help with the action economy.

As for dex based...heh it depends, you say mini campaign but how long is it?

Until level 3? level 5? level 7? level 9? level 11?

The effectiveness of classes are sometime relative to their levels.

In addition to the above questions, what is his best mental stat and is it high? Is there a theme or style? Is there any preceding challenges that would be difficult to explain depending on the villain? Any important houserules? Any class/feat/spell/item restrictions?

This mini campaign may last a 2 or so sessions (it's going to take place in the same world and time as the DMs larger campaign, so also the same characters in his campaign), and I'm not sure when I'm going to be able to do it so level is unknown (most of us are currently at level 5 though). I'm still kinda new to this so I'm currently going over all the rules to make sure I do things right.

As for the setting and story for the theme, the boss has a cursed lord template because they had killed their family to gain power over the nearby lands. They had made a deal with a devil that had gone wrong, so now hey are trapped in the mansion/castle, and the land surrounding them is cursed land so the dead there raise up. The story is, a necromancer came by, cut the boss a deal, and now the boss has an item to allow them to control the undead and use them to pillage and control the nearby towns and cities.

So the boss will have some minions throughout the manor, and a few in the final boss room too.
In this dungeon there will also be plenty of traps and puzzles.

And I thought I mentioned this, but I realize now that I've forgotten, but we are not including occult classes, or thigs that use the tech stuff.
