Diving into TFT's bell curve

[TippetsTX]

The resulting number rolled (regardless of the number of dice used) must be BELOW a target value typically based on one of the character's three attributes. DX is probably the most common since you roll against that score to hit in melee or when casting spells. Situational modifiers (positive or negative) are applied to the target value rather than the die roll result.

In other words, for task or attack resolution, lower rolls are better.

The actual relative value of attack and damage depends on the target's armor, though it turns out the math for 2d weapons is pretty simple: if net damage is (2d+x), you should raise damage if adjDX-x is less than 12, skill if more than 12, and it's roughly equal if equal to 12. Thus, for a saber (x=-2) against no armor, upgrading to a shortsword (x=-1) is equally valuable to DX if adjDX is 10. Against armor 2 (changes x to -4) you want to upgrade damage if adjDX is 8 or higher.

Ok, so 3d6, roll under DX, modified by situational factors equipment etc. I was confused by this:

Which shows 1 to 6 dice being rolled in the linked table.
EDIT: Ok, I see there are situations where you roll DX with 2 or 4 dice for special situations (like attacking a foe defending etc)

Thanks, that cleared things up.

More dice means more difficulty. For example, if your opponent has assumed a primarily defensive stance then you must roll 4d6 'to hit' instead of 3.

There are various scenarios spelled out in the rules where 4, 5 or even 6-die rolls might be required.

More dice means a greater chance of automatic success.

2d = 2.78%
3d = 4.63%
4d = 5.4%
5d = 5.88%
6d = 6.08%
7d = 6.12%

This is why Grumpy the adjDX zero wizard only attacks those who defend or dodge. If the targets are using advanced combat tactics his odds are even better.

To be clear, it's roll EQUAL TO or under. . .

While mathematically true, Henry, the increase in auto-success odds are fairly minimal. It also doesn't change the fact that the range of more statistically probable results rise significantly as more dice are added.

I don't think we want to confuse new players with your 'white room' scenarios.
