[Fantomen]

Horror marking will cause progressively stronger horrors to randomly attack the marked unit, the stronger the marking the bigger the chance of attacks and the stronger the horror. If the marked unit is a SC that can deal with normal horrors it will eventually die when the doom horrors show up. A unit with astral magic that is horror marked can have returning scripted when not in the field. Horror marking sort of forces me to use my marked SC more aggressively to get as much out of them as possible before the doom horrors show up, and to gear them with expandable gear that I can afford to lose.

But horror marking is not a way to win battles short term, so it depends on your priorities. If you decide that the goal is to just cause maximum damage while going down then horror marking is a good choice because every marked SC will eventually die sometime, if your goal is to actually survive then it isn't.

You haven't used Gifts from heaven much, that is a pretty good anti SC spell if you can boost precision. Giving a druid eye of aiming and casting eagle eyes/gifts from heaven x4 is a pretty classic anti sc tactic. Mistform will protect against the first hit but usually gets popped by it.
