Okay touch spells with the Far-out-man talent are really instead, very short range spells.
Death Punch is especially good at close range when dealing with "leakers", after using it a few times this playthrough I like using it for very short range problem solving, it also has no elemental splash effect, does a lot of damage that is crushing type so few things have good resistance- but its high level requirement, and action point cost are a downside.
Vampiric touch is a spell I am just not loving, it doesnt do that much damage, and doesnt heal you for much, it would be better if it needed no cooldown so you could do it continously until out of AP that would make it far more worthwhile and more like a vampire feeding.
