Horror mark mechanics

[Finalgenesis]

usually astral spells, a low level horror mark spell (incidentally good deterrent against awake SC pretender invasions, single target always hit) and a AoE one, astral geyser, which adds 2 mark and hit whole square but is prone to miss, it also hits around 9 AoE worth of MR AN damage.

for the attacks that give marks, it just has to hit you to give horror mark,

For reference, each horror mark I think gives you around 2% chance to get assassinate from them each turn ( dont know where I hear this from , the more mark the bigger the horror too, and of course in battle horrors go for the most heavily marked.
