Weapon size dice


Rules Discussion


Hi everyone,

it is normal that I can't find anywhere a statement about what happens if a greatsword, for example, has size increased?
The core book state that after 1d12 nothing happens...but on reddit I find several users say that after 1d12 you got +2 to damage for every size increase. Is this true?

Increasing the size of a weapon doesn't change the weapon die. You need an effect that increase the size of the die. And I'm not sure there is one that gets over d12 right now, as they are limited to certain weapon types (crossbows, simple weapons, for example).

I think the people on Reddit are indulging in wishful thinking.

PF2 clearly sets out not to have the same weapon die size madness that PF1 ran into.

In PF2 size doesn't matter anymore. Unless something specifically calls out a bonus/penalty changing the size of something doesn't do anything.

What people are most likely do is extrapolating from the Enlarge spell which increases your damage by +2.

Of course this is wrong, since bigger weapons don't do more damage (on their own).

The person wielding it gains the Clumsy 1 Condition. That is the only thing that changes. It does the exact same damage.

I also don't think it's an accident that the abilities we've seen that do actually increase a damage die have been written with requirements and restrictions that mean they don't apply to anything that currently exists with a D12. (Additionally, "every size increase" still wouldn't be valid with effects that do increase dam age dice, as a weapon can only ever benefit from one effect that increases die size).

As for the peple on Reddit, I don't know if they were talking about their houserule, or if they were just wrong.

A +2 circumstance bonus to damage was how the Playtest handled increasing the size of a d12 die. That part of the die size increase rule didn't make it to the release

Enlarge grants a similar bonus though, although for all die sizes.

The dice increasing and +2 beyond d12 is probably a relic in these people's mind coming from the Playtest, as it was like that there. But they removed this in the final game.

[EDIT] Oops, sorry, didn't refresh, Had not seen it was answered already. :x

Ooow now it is more clear..do you think this "+2 static damage" obtained from weapon size is now already calculated in the static damage that Huge+ creatures do with attacks (like for example storm giant that has a +16 static damage on hit)?

P.S: Thanks everyone for your answers!

No. Because there is no +2 static damage from weapon size in 2E. That was only a playtest thing. So it isn't accounted for in anything.

And monster creation rules don't call for itemized damage bonuses. So a storm giant with +16 damage just has +16 damage, not (+8 STR, +2 something from size +6 weapon specialization) or anything like that.


Yeah, an important thing to note is that monster stats don't add from anything.

Basically monsters have a level, and every level has a baseline of what attack, AC, etc monsters should have at that level. And they get adjustments based on what their combat role is, melee, ranged, spell caster, skill, etc.

Honestly I'm not even sure why they bothered to give them ability modifiers since you can't calculate anything with them.

You use the ability modifiers to calculate untrained skills. So if a giant with no intimidation wanted to demoralize they would use their cha mod.


I guess that's a fair point Krysgg.

I hadn't quite thought of monsters attempting something that would be rather terrible at.

That giant would likely fail to intimidate anyone who was close to their level if they relied only on their ability modifier and didn't add CR or level.

Of course there are other skills were the DC isn't set by something like a Will or Fort DC (which scales with level) and instead they might need to acrobatics to fight an enemy on a wet log over a river.
