Combo Star

Each attack grows in power the more you hit your target. You gain the following benefits:
When you hit a creature with a weapon attack, you can start a combination. If you do so, your next successful attack made before the end of your next turn deals 1d6 additional damage. This increases for each successive hit, increasing to 2d6 additional damage on the third success, 3d6 on the fourth and so on, until you miss an attack. Additionally each time you make an attack with combo star active you take a -1 on attack rolls ex 1d6= -1 to hit 2d6= -2 to hit etc. Once the duration ends or you miss an attack, you can't initiate another combo until you complete a short or a long rest.
