E6 means Epic 6 (http://dungeons.wikia.com/wiki/E6_(3.5e_Sourcebook)), and is dnd 3.5 capping at level 6, designating it as the new epic level. After reaching level 6, you gain one feat every 5000 Experience points thereafter. It's technically low/heroic fantasy without going all wuxia and super saiyan, allowign for exceptional yet still mortal characters. IMO it's the best thing that happened to 3.5<br/>D&D. Much less complication and still plenty of options and fun to be had. (Snake here knows already how I'm not fond of half-fiend half-fang-dragon half-drow lycanthrope vampire monks with 11 different prestiege classes and racial hit die with contingent finger of death tattoos on her claws and psionics to boot, but am much more along the lines of "level 5 fighter = FUCKING BADASS".)<br/><br/><div class="spoiler_container"><div class="spoiler_header" onclick="hideSecond (this);" role="button">Spoiler: Click to Show/Hide</div><div class="spoiler_body"><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">To understand E6, imagine the perspective of the average medieval peasant in a d20 game. This person has the stats of a 1st-level commoner, and while they might not know their stats explicitly, they know their relation to the rest of the world. Our peasant knows that he can be killed quite easily by maurauding raiders, enemy soldiers, or even wild animals. He’s not mighty, he’s not organized, and he doesn’t have any special skills to bring to bear when danger strikes. He worries about drought and flood, and the welfare of his livestock. His extended family likely all lives within a mile of his birthplace. To him, a trip to a town ten miles off is an expedition into the unknown.<br/><br/>Imagine you are this peasant, and you meet a trio of 6th-level adventurers. When you address the wizard, you are speaking to someone who could incinerate your home and slay all your livestock with a few words. The fighter has prevailed against a dozen orcish skirmishers and slain them all – and he could do the same again. The cleric is a man so holy that the gods themselves have granted him the power to cure the sick and heal the wounded. These are epic heroes.<br/><br/>Now consider the powers of a CR 5 manticore. To the peasant, the appearance of this manticore near the village isn’t a nuisance: the beast can, and likely will slay you in seconds if you draw its attention. You, your livestock, and your entire family are in immediate danger of violent death. Even if you were well armed and gathered a large peasant militia, your village faces heavy losses and no guarantee of success. Against such a creature, adventurers may be your only hope. E6 recognizes that 6th level characters are mortal, while retaming the game’s perspective to create a context where those same 6th level characters are epic heroes.</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div></div></div>
