==Hit Points==

Hit Points will not be figured in the normal fashion. Instead, medium-sized characters have hp equal to their Constitution score (use '5' instead, if a character has no Con score), plus a fixed number of bonus hit points per level, depending on hit die. Bonus hit points at first level are doubled for heroic characters, including the PCs. d4 grant 1 hp, d6 grant 2 hp, d8 grant 3 hp, d10 grant 4 hp, and d12 grant 5 hp. For instance, a 3rd level heroic Rogue (d6 hit die) with a Constitution score of 13 who took the Toughness feat once would have 24 hit points.

Larger characters gain bonus hit points based on size: +10 for Large, +20 for Huge, +40 for Gargantuan, and +80 for Colossal.

Smaller characters divide their ''total'' hit points by a number based on size: 2 for Small, 4 for Tiny, 8 for Diminutive, and 16 for Fine. Round up.

===Being Disabled===

In standard d20, characters are disabled (can only take a single move or attack action each round, lose one hit point if they do so) only when they hit 0 hp. We will be playing where characters are disabled at either one fifth (for heroic) or one third (for normal) of their hp total, rounding down. Thus, our above example 3rd level Rogue with 24 hit points would be disabled when they reach 4 hp.
