D&D 5E *Finally* read playtest 2 - 2d10 time!

[slobo777]

Monte-Carlo results.

This is team of three level 1 Dwarven Fighters, with Survivor specialty. They are pretty tough, so I put them through the following four encounters:

10 Fire Beetles (Average)
3 Hobgoblins (Tough)
1 Bugbear (Average)
1 Ogre + 1 Bugbear (Tough)

I chose "brave" dwarves who will abandon an adventure (defeated) if any one of the team is below half hit points with no hit dice remaining.

. . . so with no other adjustments, moving to 2d10 would appear to push results strongly in favour of PCs for combat.

I'll try to add logs of "typical" 1d20 and 2d20 adventure results, so you can get a better feel of the kind of results that count as "light injuries" versus "moderate injuries". Typically light means that the characters still have HD in reserve, and moderate means that they don't . . .

Perhaps some adjustments to monster bonuses to hit might offset the easy setting for 2d20. I'll try to check that, too.

Using 2d10 would IMO have a much more positive impact on skill rolls and checks where a difference in bonus should make a difference (arm wrestle using Str, or any skilled job where it seems silly that an untalented person might still get 25% success rate).

...Who uses a check to determine the result of arm wrestling? The higher Str just wins, in my book.

Great data, thanks!!

I'd give you xp, but you know how it goes.

...Who uses a check to determine the result of arm wrestling? The higher Str just wins, in my book.

Me too actually, but this is a hugely open-to-interpretation part of the game, and a little bit unsatisfying in the degree of choices.

We have publsihed rules of

1) High enough stat, or simply having training, is successful. Great for obvious "the character should be able to do that" situations.

2) A D20 check against a DC. Great for high stakes action with lots of chaos.

In between the two options we have . . . some vague stuff that a DM might make up e.g. "Make 2 successes at DC 15"

Generally the more rolls and successes you require, the more you home in on a specific skill value that is required to succeed - e.g. if you asked for 100 rolls at DC 16, and at least 50 successes, then there is a big difference between skill bonus +4 (18%), bonus +5 (54%) and bonus +6 (87%).

No-one wants to make 100 rolls though, so there's fertile ground between options (1) and (2) to have some interesting mechanics.

Monte-Carlo results.

Very impressive! Thanks

So from these results, and slobo777's calcs in the previous post, I think I'll use 2d10 for skill checks and d20 (RaW) for combat – guess you can say combat is more stressful therefore the swinginess of d20 is appropriate (if you even need a justification).

The really interesting thing to conclude from your numbers is that even with d20, PCs are *tough*, too tough in my book. Have to do something about that...

Take that with a pinch of salt though - the Survivor specialty makes a big difference . . . characters without it are not nearly as robust at level 1.

Not a bad plan, but I think that giving the monsters an accuracy boost to get their attacks (for at least some enemies) into the "sweet spot" where they only have to roll between 10 and 12 on 2d10 to hit would have a huge impact on their lethality. For what it's worth.

Hopefully I'll have the chance to try out the 2d10 system myself someday.

This is a second attempt to post a full adventure log. They are quite long, so I split them into two posts.

Using 1d20, 49% of the adventures were completed with "moderate injuries". This is a randomly chosen example of that typical result:
