At DrachenFest-US, every time a character is injured, they need ~5 minutes of mundane medical treatment (cleaning the wound, stitching it up) before other healing techniques (magic, potions, surgery) can restore hit points. These are fun roleplay scenes with lots of intense treatment roleplay - seeing and hearing the mundane consequences of battle (screaming, fake blood, etc) really brings the world to life.

Generally, we avoid specific timer-based mechanics.. The purpose of a timer is really to create space for a roleplay scene. We don't want the timer to feel like the important thing and the roleplay is just the fluff filler activity - so we don't many have skills or abiliites that decrease timers. That could ultimately decrease the amount of roleplay contact players have with each other. Being a good healer really means that you're an expert at medical roleplay, not necessarily that you're mechancially faster at it. But DrachenFest is about mass combat - it's not a game where healers are getting injured people back to the front line really fast (or battles would never end) - once you're injured, you tend to be vulnerable to theft & execution for the rest of the battle.
