You know the build, the 1+ save with the 3+ ward that lets you re-roll 1's (can only be killed on a 2) with the wound regenerating madness, 2+ ward against fire etc etc Our chaos player has started testing the water with "The" daemon prince build and first time I went up against it I had a go with an oldblood wielding the blade of realities in a unit of cold ones. Now my chaos player is smart so he issued a challenge knowing I had something up my sleeve. I had two choices here, refuse the challenge and risk getting my oldblood sent to the back of the unit or accept and cross my fingers. I accepted and crossed my fingers and he survived 2 rounds of combat with no wounds done before he was slain outright. I don't think combat is the way to go as the prince can just issue challenges every round, effectively keeping him safe from heroes hidden in units. (unless I am reading the rules incorrectly? can there be only 1 challenge per combat total or is it per round?) Dwellers below? means I have to take life magic and hope I roll 6 or a double on 4 dice. I've never not got it, but it's risky. The Skaven player in our group did well with magic and successfully cast Cracks Call (i think?) and managed to kill it that way so I don't know. Try and get him to charge Gor'rok? 1/3 chance of him failing a dangerous terrain test that way but let's face it Gor'rok is as good as dead if he passes and this is highly situational, the prince can run rings around Gor'rok with those wings. Care to share any experiences?
