My OOC reasonigns are this; the game where from I copied the idea had that same ruling. I never asked why it was there besides the IC universal reasoning that unique beings in abyss and hell who change too many times physical forms loose their status.<br/><br/>But IC I could see reason is simply to avoid that the unique devils/demons have naturally enemies and sometimes changing shape is best defense to avoid notice or hide from said enemies. But unable to do so (at least effectively) cuts it off as method to avoid your enemies by just changing shape. Also this means you cannot take form of another entity and bluff to be him/her with vast powers you got.<br/><br/><div class="quoteheader"><div class="topslice_quote"><a href="https://elliquiy.com/forums/index.php?topic=126755.msg5680389#msg5680389">Quote from: TheGlyphstone on 05-01-2012, 21:45:38</a></div></div><blockquote class="bbc_standard_quote">Uh...yeah, what the hell?
