GSF Trans Not Rolling Properly

[Haroshia]

I've noticed an issue with GSF Trans and stacking zoo buffs. Occasionally I will roll double 1s and instead of getting the full +6 to a stat I am just getting +5 and have to cast again. Since each cast should be providing 1d4+2 this should be impossible. Not sure if this is a known issue or if there's a workaround.

I've noticed this too. Sometimes I will have to cast the same zoo buff three times in order to get the full bonus. That should never happen, based on the math.

If I had to guess, the 1d4 is coded as cumulative and the +2 applies fresh to each cast. Not sure if that is intentional or not.

The stacking of several casts does not include the GSF-bonus - so you get:
1d4+1 two times
Then add the GSF bonus

Don't know if that is the intention, but I've been explained this is how it works.

[Svrtr]

The above is how it works, yes.

Each cast rolls the 1d4. The flat bonus is separate. If you cast twice and get 1 twice, you would get

1/1d4 +1/1d4 + 2 for a total of 4.
