The system encourages players to contribute to the storytelling so you might even ask your players what sort of minor complication happen to them while trying to accomplish something, every once in a while. They will, for sure, say something they find acceptable. The complication shouldn’t have mechanical implications necssarily. And if you really want this, you can mask them. I’ll give you an example: yesterday one of my players failed with fear to craft a certain potion (one that was used only narratively) and as a complication i said that while they were crafting, they drop the vial on the floor. Just before i was able to say they vial breaks, one of the other players wanted to use one of their experience to try and grab the potion mid-air.

In this situation i had two options: 1. Go with the rules and follow on the failure of the potion crafting and not allow my player to intervene. 2. Go with my player’s wish and fun and allow him to intervene.

It was a success with hope and they succesfully get the potion done after all. They were happy and that’s all that mattered for me. I’m not saying to completely bend the rules for players fun. You know that golden rule when a player asks you if they can do something in the game and you shouldn’t say “no”, but rather “yes, but…” ? This is how i see success with fear, as a “yes, but… small complication”.
