‎Explanation from the SAM + Spetsnaz discord
‎
The effectiveness of the Prismatic Set depends on your Temporal stat: the higher this stat, the stronger the bonuses and the faster the stacks accumulate. The key mechanic of the set is the Spacetime Tuning effect; it triggers every 20 seconds and grants +0.2% Total Damage per stack, up to a maximum of 100 stacks (for a total of 20%). The trigger interval of 20 seconds remains unchanged, as does the maximum limit on the number of stacks. The only thing that changes is how many stacks you get each time the effect is triggered.
‎
‎Thanks to the full set bonus (6 of 6 items), every 2500 units of the Space-Time statistic add +1 additional stack each time the Attunement is triggered. For example, if you have 32,500 Time-Space, you divide 32,500 by 2,500 to get 13 extra stacks; adding the base 1 stack to this gives you a total of 14 stacks every 20 seconds.
‎‎To reach the maximum limit of 100 stacks, it will take approximately 7.14 ticks, which is approximately 143 seconds (approximately 2 minutes and 23 seconds). Without this scaling, the process would take about 33 minutes; Thus, the set does not speed up the timer itself, but increases the number of stacks per trigger, allowing you to achieve the same maximum bonus to Final Damage of 20% much faster. This Total Damage bonus applies to absolutely everything, making it a powerful and versatile damage booster once fully stacked.
