Question RE: "Swift Regeneration" Talent
I'm prepping to run my first Cosmere RPG campaign, and when reading through the surge talents I found a confusing piece of the "Swift Regeneration" talent under the surge of Progression. The talent's description reads "When you use Regenerate, instead of recovering the normal amount of health, you can recover health equal to 1d6 + your Progression modifier. The size of this die increases with your ranks in Progression: at 3 ranks, roll 1d8 (instead of 1d6), and so on."
From my understanding, the "normal amount" is 1d4, which is the base rank 1 size of surge the surge die, which lead me to believe that "Swift Regeneration" lets Progression-users health themselves for 1 die-size greater than others (i.e., at rank 1 they would heal themselves 1d6 instead of 1d4, at rank 2 they would heal themselves 1d8 instead of 1d6, etc.). But then at the end of the paragraph it says at rank 3 they would heal 1d8 instead of 1d6. 1d8 is the standard die size for surges at rank 3, so my question is: does "Swift Regeneration" scale to one die-size larger than the standard surge die at each rank, or does it only give you a benefit at rank 1 when your die is 1d4?
Thanks for any help.
