Can be purchased from The Quills for 10,000 Standing 10,000 upon reaching the rank of Instrument.
The critical damage multiplier bonus is multiplicative.
This arcane pairs very well with the Lohrin Brace/Certus Brace, Shraksun Scaffold, and Granmu Prism due to their innately high critical chance and critical damage complementing their already high base damage. The Shraksun Scaffold and Granmu Prism's area-of-effect attacks in particular allows them to hit more enemies, allowing for more chances to deal critical hits.
Prior to Update 24.6 (2019-04-04), Virtuos Strike was purchasable as a blueprint with the following requirements to build:
We’ve adjusted the values of older Arcanes with the goal of making lower rank Arcanes more viable, and more desirable while collecting as a result. In short, there are three stats that each Arcane tends to have (speaking generally) -- for example, a percentage chance, a stat buff, and the duration of the buff.
Certain Arcanes increase all of these stats per rank (making them scale exponentially), but we are changing it so that only one stat is affected by rank (making it scale linearly). The other stats will now be at the max-rank value regardless of the Arcane Rank, thereby buffing lower-rank Arcanes as a result.
On Critical Hit: 20% (was 5%) chance for +15%/60% Critical Damage for 4s (was 1s)
