I will start read/reply in more actively tomorrow, this point trying catch up with other projects outside E during winter break. But to answer some immediate questions/ideas presented;<br/><br/><span class="bbc_u"><strong>Cults</strong></span><br/><br/>Cults I had planned work bit same like running business in DMG II, you make roll (with modifiers) and if passing certain cap, you get that number of souls (1 HD per soul unless you want write story how you sacrificed a 20 HD individual instead 20 different people over course of a month). Leadership helps establish cult quicker and gives lasting modifier (loyal cultists make establishing one easier and keep it control so long leadership of cult is part of follower roster).<br/><br/>There is some material costs involved in making cult locations and thus works as material investment (and drive everyone seek material wealth gains).<br/><br/>What use are souls? I am planning souls are used to buy troops/extra followers (mostly outsiders as souls coming to you start go through usual planar rebirths to proper outsiders). Souls are used to build features in planes (buildings and such or special locations). It also can provide nourishment/food (for Ungrath example, could demand any fey-blooded individual counts as meal so long there is plenty HD added in while pure feys are delicacy).<br/><br/>Souls ofc can be also used hire mercenaries (cheaper than creating own followers but mercenaries work for one month before need paid again with souls). However soul system details I haven't wrote down as these are just ideas. In normal canon is mentioned souls = to XP to Archfiends (Grazz'zt gains level when he devours +5 million souls example). But our XP and such is not tied to souls so had to get ideas how else spend them and thus far upgrades to Soul Casket, planes and such is base.
