If the Harm effect hurled a chunk of rock at a target, then I'd compare the character's Speed (x2) to the area affected by the spell (how big is the chunk, etc), and guesstimate if the target can use "Dodge" DP. Or just say the target can use Dodge if it makes more sense to do so.
Okay, let's assume you have a spell effect that hurls a small rock, like the size a human could throw (why you'd design a spell that only does that, I have no idea, but let's assume it's a normal Harm effect spell).
Yes, a Harm effect spell using the "bolt" sub-type.
It totally makes sense to me that the rock could be evaded or deflected, and possibly even parried depending on what weapon is being used. And I can think of a number of spell effects that would follow this model...is there a better way to represent this kind of spell than a Harm effect? If not, do you think it would be unbalancing in any way to allow Harm spells to work exactly like weapon attacks (damage goes straight to Toughness, but can be avoided with any ADP)? Basically, a new aspect option for Harm spells that the spellcaster would choose when the spell is created?[/quote]
What you said makes sense yes. But if Active Defenses were allowed in such a way, it would be tough keeping the rule that Harm spells affect Resilience then Toughness. I'd say a spell would allow defense by means of ADP *or* Resilience, depending on the type, if such an optional rule were active.
Maybe when creating such a spell, if a Harm Effect, it can be created in such a format:
(A) Mitigated by Evade, Dodge, or Deflect, then Armor, then Toughness. Works just like a regular weapon attack. Resilience would not factor. Manifestation would have to be physical matter, and not of a nature normally reduced by Resilience (like elemental forces). A projectile rock is a good example. Spell cost follows standard rules.
(B) Mitigated either by Dodge and/or Resilience, bypass armor, then Toughness (the norm).
(C) Mitigated by Resilience only, bypass armor, then Toughness.
(D) Mitigated by Resilience only, and once Resilience drops to zero, effect takes hold.
