Hero Chips

For my upcoming game of dnd I wanted to use the optional rule from the DMG (page 264) for Hero Points. Players can use them to be more heroic in some events.
For this I wanted some visualization, so I made these Hero Chips.

The max any player can have is 15 (5+half lvl), so I made a complete set for one player with a little holder to put them in during play to see how many are left.
