You could also base it on something similar to Space Hulk, but that would (again) require custom rules for pretty much everyone since we have neither Marines nor Genestealers to work with. (Although one idea that I have for a character would be a human/Tyranid mix that could be the result of an experiment)<br/><br/>I actually went and calculated it out, and Wil would need rules from 7 different D&D expansion books, not counting core books:<br/><br/>Dragonborn race from<span style="font-style: italic">Races of the Dragon</span><br/>Swordmage class and Master of Nine prestige class from<span style="font-style: italic">Tome of Battle</span><br/>Divine Crusader and Stormlord prestige classes from<span style="font-style: italic">Complete Divine</span><br/>Custom weapon from<span style="font-style: italic">Weapons of Legacy</span><br/>Miscellaneous abilities and items from<span style="font-style: italic">Dragon Magic, Draconomicon</span>, and<span style="font-style: italic">Stormwrack</span>.<br/><br/>Keep in mind that this is just to get certain abilities that he has, and especially with the prestige classes is only for one or two.  This is also when he is at his absolute full power, which he is nowhere near currently.  I'm tempted to give him levels in Divine Emissary from<span style="font-style: italic">Epic Level Handbook</span>to match his background better, but I think that's just overkill at this point from a game standpoint, considering his ECL would already be above 30, which is horrendously powerful for what's happening in the story.  I guess it just goes to show what can happen when you try to fit a character to a game, rather than design the character<span style="font-style: italic">in</span>the game and then just extrapolate from there.
