Simple Followers

As I've played 5E D&D but continued to read a lot of OSR stuff, I've noticed that OSR games seem to commonly assume that the party is tooling around with the usual 4-8 PCs but also a large number of followers--paid henchmen willing to pepper enemies with sling stones and bolts, and hirelings brave enough to not drop their torches when the spells start flying.

I don't think I've played a single game of 5E where a player bothered to hire a follower, despite how useful it'd be to have an extra hand for carrying your lanterns and ten foot poles.

I'm not entirely sure where this divide comes from, but I suspect it arises from two major places:

1. Differences in lethality between 5E D&D and old-school games. If you're fragile, you want lots of support; gold is common, but blood is precious. 5E characters are FAR tougher than characters in any OSR game I can think of, so they have less concern over frequent and/or arbitrary death.
2. Combat complexity. 3E, 3.5E, 4E, and Pathfinder all seem to require a lot of mental processing power to parse and resolve a combat round; every additional actor on the battlefield adds more than a flat value to the complexity of combat resolution. Clogging up the field with entities that are less important than the PCs and their deadly foes has a poor return on conceptual investment.

In the interest of simplifying the use of both combat-ready followers ("henchmen") and non-combat followers ("hirelings"), I took a stab at writing some streamlined rules. I was mostly thinking of 5E as I wrote these, but I believe they'd work for something like Dungeon Crawl Classics as well; the more conceptual distance between games like that and what you're using, the less confident I am that they'll parse without additional effort, but I'd love to hear about your experiences should you give them a go.

Simple Followers
Playtesting Status: Pure theory. Looking for an opportunity to try it out.

Followers are any mundane NPCs that you've hired to assist you in your adventures, either by fighting your foes with you or providing utilitarian assistance like holding light sources or carrying extra equipment. If the person you've hired to tag along sounds like they deserve more detail than that, they're not a follower--give them a real statblock and play them like a full-blown NPC. Otherwise, keep reading.

You can command a number of followers equal to your Charisma modifier (minimum 1).

Your followers are real people who are physically present in the dungeon and on the battlefield, but they don't take up a space on the battle grid. They don't count as allies if you have any abilities that require an ally to stand adjacent to you or an enemy; they're just not competent enough to present a credible threat.

(Yes, this is specifically so that 5E Rogues aren't automatically able to land sneak attacks without party support.)

Rather, your followers are always near enough to you that an AoE that hits you hits them, but far enough away that they generally don't get in the way of your fighting and movement.

Each follower has 1 hp; if they take any damage, they die.

(Don't waste time worrying if you can heal them. You have more interesting things to think about.)

At the START of your turn, your followers do things:

• Hirelings holding equipment for you keep up the good work.
• Henchmen wielding melee or ranged weapons help you attack your target in combat. 
• The player picks the target for the henchmen. Henchmen won't attack something that would be obviously and immediately lethal to strike, like a golem made out of burning chainsaws. If you're still not sure if they'd go for it, resolve it with a morale check.

Resolve all henchmen attacks at once by rolling a single d6:

• On a 1, your henchmen got in the way more than they did anything useful. Your next attack has disadvantage as you re-position yourself. Bloody peasants.
• On a 2-5, their enthusiastic but untrained blows helped you land a solid hit. The next damage roll from any source made against the target they struck has advantage (roll damage twice and take the better result).
• On a 6, your coterie of turnip farmers managed to land a lucky shot on your foe. The target immediately takes 6 + [the number of followers in your group] physical damage. The player should pick a type of damage that makes sense based on what the followers are wielding.

Graduation
Followers remember their lucky shots, and eventually they get cocky enough to think of themselves as proper warriors. They might even be right.

Keep track of how many times you roll a 6 for your follower attacks--just scribble down some check-marks somewhere on your sheet and label them "Graduation". When you've rolled a total of three 6s (they don't have to be consecutive), one of your followers "graduates" and should be run as a fully-statted NPC. Give them a full name and a proper NPC stat block. Don't give them levels in a PC class, though--even if they're wrestling in the mud for a rusty shiv, the PCs should remain the stars of the show.

Rather than hireling wages per day, graduated followers will start requiring an equal share of the party's treasure. If the party is willing to provide that, they'll stick around. Otherwise, the newly-minted bravo will most likely head off in search of further adventure on his or her own.

If all of your followers die because a Lizard Priest puked acid vomit all over you and yours, erase all your checkmarks--your dudes are smoking paste, and it's time to hire a new batch. RIP.

Follower Morale
These rules probably work best if you're also running a morale mechanic for followers; if that's the case, the PC controlling the followers counts as a leader, so add their Charisma modifier to the morale check made by their followers.

This subsystem shouldn't take any longer to manage than checking the number of followers you have, rolling a d6, and moving on to your PC's actual turn. If it gets more complicated than that, reconsider how you're using it.

A cheap and easily-replaceable source of advantage on attacks in 5E D&D would be extremely powerful, which is why advantage is only granted to damage rolls. Even if you tweak other aspects of this system, I'd encourage you to leave that one alone if you're playing 5E.

Anyway--thoughts? Gut reactions? I'd love to hear if this sounds like it solves the problem I intended for it to solve, and if it's something you'd use in your own game. Sound off in the comments!
