Daemon Summoning Points
(Rule)Description: Points are earned differently per each god.
Khorne: Each hit scored by a Chaos model in close combat scores 1 Khorne summoning point. Models with the Mark of Khorne score 2 points per hit
Nurgle: Each wound inflicted on an enemy model by shooting or in close combat scores 1 summoning point. Wounds inflicted on the enemy by models that bear the Mark of Nurgle earn 2 summoning points.
Slaanesh: Every time an enemy unit takes a Leadership test for any reason then you score a number of Slaanesh points equal to half (rounding up) of the Leadership value of the unit taking the test. If a model with the Mark of Slaanesh forces the test they get the full value instead of half.
Tzeentch: Each force card used by either side in the psychic phase scores 1 point (Ultimate Force is worth 3). Models that bear the Mark of Tzeentch earns 2 points rather than 1. Force cards discarded unused do not earn any summoning points, but force cards used for psychic powers that are nullified do count
