Creating a D&D Combat Tracker

As a DM, preparing and running combat encounters can be time consuming, challenging and stressful. Shieldmaiden (formerly known as Harmless Key) stream lines combat leaving you with more time to focus on the story you want to tell with an encounter.
Shieldmaiden makes combat a breeze by keeping track of everything a DM needs during combat, from hit points, initiative and AC, to concentration checks, conditions and surprise rounds. Making combat faster, more accurate and hassle-free.

Shieldmaiden is created by two experienced Dungeons & Dragons players from Amsterdam. We were missing an encounter tracker that tended to all our needs, so we decided to build one ourselves.
After some positive feedback from our fellow D&D players, we decided to share it with the public in February 2019.
Since then we've been improving and expending a lot and this is still going on.

We hope you get as much use out of Shieldmaiden as we do.
