Throw a Powder Keg as an Improvised Weapon.


Rules Questions


As the title reads, can I throw a powder keg using the Improvised Weapon rules? Had a GM tell me no, while the VC sitting at the same table said yes, and the GM chose to ignor the VC's ruling.


Sure. It won't explode and would likely waste all the powder, but I'm sure you could.

Also, table GM > VC.


Gunpowder actually requires a good enclosure to explode particularly well.

There aren't rules for lighting a powder keg on fire to cause it to explode...if I was feeling generous I might let you do it improvised for the same damage as an alchemist flask.


An improvised thrown weapon has a range increment of 10 feet.

A powder keg needs to be exposed to fire or electricity in order to explode and when it does explode, it has a blast radius of 20 feet (for 5d6 points of fire damage).

Under the right circumstances, throwing a powder keg could be quite interesting.


Well, my character in question has a Laser Pistol. Throw the powder keg and then shoot it for 1d8 fire damage :)

And expensive if it's one that belongs to the party's gunslinger :)

Do you have a source for this or are you making it up?


It's taken from Ultimate Equipment.

Ultimate Combat for the rules regarding powder kegs; the CRB for the rules regarding improvised thrown weapons.

Shoot at it on the next round. Still, I'd allow it at my table. But expect variation.

And hope the powder keg didn't break open when you threw it.


Heres link to the Black Powder that Eazy-Earl was referencing.


1d8 isn't getting through wood at 1/2 damage + hardness, unless laser beams have some rules for that?

If a GM rules that a powder keg is of similar construction to a small chest (hardness 5; hit points 1) and said GM rules that fire does full damage to such a wooden object, it'd be quite easy for a laser pistol to pierce a powder keg with one shot. But again, expect variation.

If the keg were thrown less than 20 feet, I'd probably be more lenient and rule in the player's favor.

It could add +5d6 to the next fireball :)

Jegus, it's an expensive improvised grenade that requires two rounds of action and a weapon obtainable only from a meatgrinder 3-7 that could become nonfunctional by glitching at any time.

I get it that everyone's too cool for leniency school and a tad too enamoured with their own words, but I'd cut this guy some good ol' slack.

What if you stuff an alchemists fire in the barrel?

Anyone cool enough for this tactic is going to dual-wield their powder-kegs and laser pistols, and get this off in a single round, penalties be damned! :)

This is the kind of situation where the GM should always try to say "Yes, but..." rather than "No."

Shadow Lodge

That's actually a pretty decent way to get it off. Sure there're penalties, but you only need to hit a square (ac 5) and then hit the keg's touch AC (0?).

Well sure enough.... those rules are not particularly realistic IMO (but what is in this game) but they do exist.

I had no idea they covered that.

In this case, do keep in mind that thrown weapons can only be thrown a maximum of 5 range increments (50ft in this case) and that every range increment causes a -2 penalty to attack rolls. Assuming we're using splash weapon rules (despite not actually being a splash weapon) if you miss you roll a d8 to determine which direction it goes and it travels and then count from the targeted square a number of squares equal to the number of range increments.

Also don't forget not having precise shot or improved precise shot can add a further -8 penalty to your attack roll, depending on the tactical situation.

Hence, expect table variation. I'd allow someone to throw the keg; not sure I would allow someone to blow it up with one shot automatically, but I'd let them try. "Yes, and..." sometimes means, "Yes, you can try that, but it doesn't work very well and you wind up wasting your time."

Having said that... if you did max damage and blew up the keg, 5d6 damage would also be applied to every unattended object within the explosion range. I hope you weren't hoping to recover any papers or notes or artifacts from that area, you know, as Pathfinders are wont to do.

Sometimes it's better to ask, "should I?" than "Can I?"


Also, if the player didn't have Ultimate Combat and the Technology Guide out on the table in advance of asking this question, I'd just say, "No" and move on, as well.
