I'm working on a racial archetype for the spell-less ranger (from Kobold Press) and was wondering if a limited uses per day (was thinking 3 + Wis rounds/day) would be a viable alternative to the stealth attack ability (similar to sneak attack), with damage increasing at the same levels.
Essentially, I want to try and replace the stealth attack ability with an equivalent to the shock weapon property, increasing in damage at the same levels and eventually upgrading to shocking burst later on.
Does this seem balanced, too powerful, or not powerful enough (which I'm okay with as give me more play with tweaking the archetype)?
Whats the damage exactly? Equal to the stealth attack?
I was thinking possibly. One option is for it to scale up in damage the same levels that stealth attack does. If that seems too overpowered, I'd of course set it back to the standard shock property and shocking burst at 10th lvl or so.
