A class’s HP is some base + Constitution. Base HP is almost always 4, 6, 8, or 10. - Dungeon World pg347

• 4 base HP makes for a class that is deliberately fragile, they’ll need help from others when the swords come out.
• 6 base HP is for classes that aren’t ready to fight, but can at least take a hit.
• 8 base HP is enough to take some hits and get into combat a little
• 10 base HP is for skilled warriors and those who have no fear of battle.

Damage is chosen from the dice available: d4, d6, d8, d10. The Dungeon World classes all use a single die with no static bonus, but there’s no reason not to experiment with other options: 2d4 or 1d6+2, for example. High HP and damage tend to go together, but your new class could be a pacifistic brick wall or a glass cannon—fragile but dangerous. - Dungeon World pg347
