Dice progression (not size)

[SethFahad]

Hello everyone.

We are playing the d20 Blood and Fists and some feats and Martial Arts Masteries give you an increase to your damage die.

So for example a 1d4 becomes 1d6 etc.

Now my question has to do with a Katana. A Katana does 2d6 (according to the rules of the specific game). I am a bit confused and (admittingly) rusty in my rules understanding. What is the progression on a 2d6 damage?

For you convenience the Slash feat maneuver says: "Your weapon damage is increased to the next larger die."
The Martial Arts Mastery feat Hard Katana 1 says: "The damage from the designated attack increases by one die size (e.g. from 1d4 to 1d6)."

What happens when we combine these two or other similar feats (like Hard Katana 2 with another increase)?

Hard Katana 3 says something different: "Your attacks deal an extra die of damage (e.g. if your kick attacks deal 1d8, they now deal 2d8)."

2d6 with Slash becomes what? 2d8? (size progression says 3d6 but this is not size)

2d6 with Slash and Hard Katana 1 becomes what? 2d10?

2d6 with Slash and Hard Katana 1,2 and 3 becomes what? 3d12?

Please help, I am lost. What is the die progression?

I believe any time there is an increase you use the size chart. Also if the source you are using (3rd party?) does not explain it plainly then defaulting to the size changing rules is the most reasonable course.

Official SRD Table: Weapon Damage by Size for Medium size weapons says:

1d2, 1d3, 1d4, 1d6, 1d8, 2d4, 1d10, 1d12, 2d6, 2d8, 2d10.

It stops there. I need more steps of advancement. What follows after 2d10? And after that? And after...? ...

Weapon size chart for 3.5e. (http://www.d20srd.org/srd/equipment/weapons.htm#weaponSize)

P.S. Savage Species also has a bigger chart for weapon sizes, but it doesn't sound like it's what you're looking for.

Thank you for the reply. I found it really useful. I wonder where did you find this table.
Not wishing to take advantage of your kind willingness to help (although I am:smallbiggrin: ) can you please provide a couple of additional increases of dice. So, 2d6 - 2d8 - 2d10 - 2d12 - .... - ....????

Yes Savage Species has a size progression chart. It won't do unfortunately...

I didn't find it... I made it. :smallconfused:
A set of die in the d20 system comprises the following die: d4 (average 2.5), d6 (average 3.5), d8 (average 4.5), d10 (average 5.5), d12 (average 6.5), d20 (average 10.5).
For weapons, you usually only need multiples of 4- to 12-sided die, with bigger weapons using multiple smaller die and smaller weapons relying on virtual d3s or d2s. On the other hand, if you're playing in a system with a rule that simply increases the size of a die instead of the size of a weapon, you just use a bigger die (this usually increases the average result of 1, except when you jump from d12 to d20). This also means that such a system gets weird if you try to increase the size of a d12 or a d20: you can use a dice roller app so that you can progress organically (turning d12s into d14s, d20s into d22s, and so on), but the game you're playing most likely has some guidelines for how to handle these scenarios in the combat or weapon section. If it doesn't, your guess is as good as mine.

Some of the progressions in the game are illogical mathematically, but overall they follow the concept of increasing average damage dealt. You can generally anticipate the next increase if you know how to determine the averages of possible rolls:

1d4 (2.5), 1d6 (3.5), 1d8 (4.5), 2d4 (5), 1d10 (5.5), 1d12 (6.5), 2d6 (7), 3d4 (7.5), 2d8 (9), 4d4 (10), 3d6 (10.5), 2d10 (11), 5d4 (12.5), 2d12 (13), 3d8 (13.5), 4d6 (14), 6d4 (15), 3d10 (16.5), 7d4 or 5d6 (17.5), 4d8 (18), 3d12 (19.5), 8d4 (20)...etc...

There is a nice explanation of the math which you can read here (https://anydice.com/articles/dice-and-averages/).

However, the official tables don't always follow the expected progression exactly.

Just follow the pattern...
2d10, 2d12, 4d6, 8d8, 8d10

basically if 1d10 advances to 1d12 then..
1d10 + 1d10 --> 1d12 + 1d12 = 2d12

There is also a much larger table in Arms and Equipment Guide. IIRC.

Dice progression and size progression are the same thing. You're defining a difference that doesn't really exist otherwise.
