Okay so I understand all the new rules for summoning with the points. However I thought I have read somewhere that if you were to summon a unit that costs... lets say 6 points and you have 12 points. You would lose the left over 6 after the summon. But I cannot for the life of me find where I saw that. Is this true? Or do you maintain any unspent points for future use?
I don't recall such a thing for us. We can even summon different units in the same turn. IIRC that thing works for Blood Tithe Points for Khorne: if you spend any Blood Tithe points, then any left over are immediately lost
