The Iskaria Sagas
Very Exciting! Table Rules!
1) You can take multiple potions at the same time. Their effects may mix.
2) At a long rest, you heal no HP but will regain all spent HD
3) Spending any number of HD to heal costs 1 use of a Healer’s Kit
4) Upon taking 20hp or >half of your character’s max hp (whichever is greater) in one hit, your character receives a random scar
5) If dropped below 0 hp, you have the option to take a scar to immediately return to combat with 1 hp
