Let it do the math

Tap a monster's HP. The calculator applies crits, armor, vulnerabilities and minion overkill, and shows you the sum before you commit. Bloodied and Last Stand pop up when they happen.

The HP calculator open on a Quicksilver Hound, showing 9 damage plus 10 for vulnerability before it is applied

Stat blocks pop up over your note

Click any monster or NPC and their sheet opens over your note, with HP, turn and actions. Close it and you're right where you left off.

Your adventure, your NPCs and your homebrew monsters are text files in a folder you control. Ember Vault adds the tools on top. Turn the plugin off and every note is still there, still readable.
