As most of you probably already know, End Times: Khaine has introduced some drastic changes to how the magic phase works in warhammer. I'm not sure I can post a complete summary as I've only had one game, but the key points are that we now roll 4d6 for PD,every magic caster knows all spells from their lore (effectively Loremaster), can cast each spell mutliple times and the casting attempts have a random (d6) maximum of dice you can use.
As this is all very new, I'd like for you all to share you're experiences of using these new rules.
I've played my first game with End Times magic today. Battle Line scenario rules. My CD took Hashut and Metal, while the DE took Shadow and Death (warlocks know all spells from the two lores). In general the magic phase worked well. The difference in number of PD didn't influence the game too much. If anything it made things less random and reduced the number of unbalanced phases (like 4vs2, where one side just rolls 4 dice and theres nothing you can do). The random number of dice to cast means the small spells were cast most of the time - stuff like soulblight or Withering were spammed a lot. No single big spell made it thorough, though a number of purple suns and flames of Azgorh were attempted.
All in all, taking into account the limitations we had, the new magic phase wasn't bad. I'm looking forward to how it will look in future games.
Further, it seems reading Khaine that this revised magic phase is only used when playing ET rules or a combined Elves army (please correct me if I'm wrong). This makes for a very interesting/ difficult discussion on how this will effect Tournaments moving forward.
