attribute modifier vs/or xd6 rolls

[sekalo]

I want thank everyone for their help, and welcoming me to the TFT forum with such great help and support.

I have a similar question on the GURPS forum going and to be honest, it seems like it is much more complicated to get what I am after with GURPS, then with TFT, so I might have found my system in TFT.

I am sure it is due to me not fully understanding GURPS, since I really never played it. At first I was using GURPS Lite, then I found Ultra-Lite. I was very happy with Ultra-Lite with some table judgement calls since GURPS just seemed so complex and I stripped a lot out. Since I did not like the Dodge/parry rules I created a chart that took the attacker's hit probability, compared to the probability of the defender for parry/dodge/etc to have a target number to roll since I wanted something like D&D or Classic Traveller combat to be fast.

Then I found TFT and was sort of hooked and tried to find all items I could, thus leading me here. Not only did I realized that I forgot totally about this game, which I played 40+ years ago; when I left fantasy hex-map combat for Scifi hex-combat in Battletech.

I just need to get a good grip on the dice penalties when rolling against x/DX for example.

GURPS does have an example on the -x/+x modifiers based on task difficulty. Does TFT have anything similar to that? I have found a suggestions for the 'x/DX' difficulty but not really for the '-x/+x' to stats modifiers. Not sure what you call these type of modifiers, but the kind used in Shostak water combat post.
