Stealthy Attacks

[Nytmare]

I'm about to pass out, and don't have the brain power to do anything but come up with the idea, but what kinds of horrible things would happen if you tried to make a system that used some kind of stealth roll vs perception all by itself as an attack, instead of having to follow up a stealth roll with an attack?

I've been up for a day and a half and don't think I have the mental faculties to even try looking at the numbers...

Imagine if you had a feat that gave you +5 to hit, and another feat that stacked with it to give you a further +2 to hit.

That's basically what it will do: turn skill training and skill focus into +hit bonuses.

What if it was an outright trade off between attack bonuses and skill bonus? Something like:

d20 + Stealth vs Targetted Defense + Perception?

I don't know if this is gaining me anything though. It's one less roll, but it's probably complicating the "what number do I have to beat" end of things by an equal amount.

This is true. You also gain the benefit of any skill-enhancing items. But you give up proficiency bonus and enchantment bonus as well as situational bonuses like combat advantage. The net bonus might not be that great.

+5 Skill training
+3 Skill focus
+1/5 levels Item bonus to skill
-3 Proficiency bonus
-2 Combat advantage
-1/5 levels weapon enchantment bonus
-1/10 levels Weapon Expertise

This sums out to
+3
-1/10

Not excessive.

A bigger issue for me is that you should probably base the difficulty on the highest of the normal defense and 10 + Perception.

And how does this work for different powers?
