We have Critically Fast for Pathfinder, so let’s make it for DnD 5e.
You move so fast you’re a blur to the eye! Gain the following benefits:
- Increase your dexterity by 1 to a maximum of 20.
- Gain a +2 bonus to initiative checks.
- When you roll initiative at the start of combat and you roll a result that would normally be a critical for you, you gain advantage on all dice roll for the first round of combat. If you would normally have advantage at the start of combat due to class features or being hidden, you gain advantage during the first and second rounds of combat.
