I discovered this excelent mode recently with a friend and I have one problem. We have just finished the game in terror on the ladder. We started to make our mid-game stuff and we started the black road challenge in order to unlock our last skill which is a survivability skill. We want to do that before starting destruction mode.
All is find except that, now we have to defeat king koth. We can't cast a dark portal because we need a book of summoning. I follow the guide of ScarletEdge about fire paladin unholy caster. He wrote that we can drop this book on the summoner in terror but I think it's not true right now. I read some info about cubing 3 meditation candles + 3 victims hearts but I'm not sure it's true too and I don't know where to find these items. All this is not clear for me.
Please don't say me that it's only droppable on the summoner in destruction. It will be a non-sens.
