The Age of Warriors (Project Revived!)

[Elves]

Gaining the patterns as you level doesn't feel quite right.

On the other hand, if I think about a 1st level character learning to play this class, having to memorize all 4 patterns from the get-go is a high barrier to entry. Personally I would space it out so that you learn 1 per level for the first 4 levels, or something similar to that.

I think I'll go with remaking the Gunslinger.

And there are valid reasons to remake it, too. The Grit-Deeds mechanic, like a lot of PF's "point pools", seems a little bit annoying to track and a maneuver system could be a better experience. Meanwhile, the other half of their class abilities are just bonus feats which is kind of lazy.

Gunslinger sounds good, but are the rules for firearms going to be the same?

Pathfinder makes guns into ranged touch attacks, though I read that in the first draft of their gun rules, guns would instead ignore a certain amount of armor/natural armor when rolling to hit. So you could do that, and give guns a "penetration" value -- penetration 5 means you ignore 5 points of armor or natural armor, or 5 points of each (depending on whether double dipping is allowed). But for abstraction's sake it may be fine to stick with DMG rules -- remember the average IRL person has 3 to 10 hit points, so they're going to be dead either way.

Primal, it's up to you if you want to do the armor penetration thing or just roll with DMG stats.
