Card Text/Abilities Edit
When attacking, you may spend a focus token to change 1 of your focus results to a critical result.
You may only use Calculation once per attack, no matter how many focus tokens you have to spend. However, If you roll multiple focus￼ results during an attack, you may spend 1 focus token to change 1 focus ￼ result into a critical result (using Calculation) and a second focus token to change all other ￼focus results into ￼hit results (the normal effect of spending a focus token).
