Roll For Assist is here to help with your game of Dnd. Use the numbered squares to roll , d4, d6, d8, d10, d12, d20, or Percentile (d100). Use the plus and minus buttons to inflict damage or to heal by one at a time, or put in the box how much you'd like to heal/damage. Tap the character name at the top to add, delete, edit, or switch between characters you have created. They will all have their own max hit points, and their current hit points will be saved so you can switch between characters and close the app without having to remember how many points you had last session. You can use the long rest button (Moon with the zzzz's) to reset back to your Max HP.
