(TFT) d20 TFT Battle Report

["Ty Beard" <tbeard@tyler.net>]

Ran a number of d20 TFT battles today (a series of 2 on 2 gladiatorial
bouts, with a grand battle at the end). Played well and standard Melee
tactics seemed to work well. Some observations:

1. Very low AdjDX characters appeared (AdjDX 6 was the lowest serious
character). But because the d20 allows even these to be effective, they did
okay.

2. After each bout (4 total), each gladiator got an attribute point to add.
The players appeared to choose DX a bit more than half the time -- say 60%.
This compares favorably with past experience where players take DX about 90%
of the time.

3. Using the standard negative modifiers *seemed* to work okay. But I did a
statistical analysis and discovered that a -1 DX modifier reduces the chance
of success an average of about 9.1% (using a DX range of 6 to 15). This is
roughly linear, so a -2 DX modifier reduces the chance of success an average
of about 18% and so on. This would imply that each -1 DX in Advanced Melee
should be a -2 DX in d20 Melee. Further testing will be needed I think.
Unless of course, one thinks that the DX penalties and bonuses are too
severe/beneficial as is.

4. Also, running a statistical analysis on the effects of adding a die to
the difficulty of a task indicates that adding 1 die of difficulty reduces
the odds of success an average of 28%; adding 2 dice of difficulty reduces
the odds of success an average of 46% (again, assuming a DX range of 6-15).
So perhaps 4 die rolls should be treated as -5 to the roll; 5 die rolls
as -10 to the roll.

Thoughts?
