Introduction
The Fairy Trickster feat offers a splash of extra mobility plus a powerful on-hit debuff that will make your target easy for your party to quickly defeat.
Because Flustering Strike is only usable PB times per long rest, you may want to wait until your Proficiency Bonus improves to take the feat so that you’ll get more value out of it. Waiting until level 8 or even 12 is totally reasonable.
Ability Score Increase
This will limit the variety of characters who can use this to classes likely to be tricksters. Rogues, Sorcerers, and Warlocks are obvious choices, but Monks and Dex-based Fighters and Paladins are also good choices.
Fairy Trod Trotter
Neat, but probably only useful for Monks and Rogues. The benefit is situational by design, and you’ll likely go long periods without it being useful unless your party likes to create difficult terrain.
Flustering Strike
Only PB times per day, but still incredibly powerful. Use this on high-priority targets, then have your allies drop a whole bunch of hurt if your target fails their save. Follow this with your party’s favorite save-or-suck effects, such as Topple weapons, Stunning Strike, spells like Hold Monster, etc.
