Half-Giant (Race)

The "Exceeding Level Limits" optional rule from the DMG is mandatory in DARK SUN campaigns. However DMG Table 8 is replaced with the "Exceeding Racial Level Limits" table from the Dark Sun Campaign Setting Revised book.
Special Advantages:
* A half-giant character doubles their Hit Die rolls, no matter what their character class is.
** Add any bonuses for high Constitution scores after doubling the roll of the die.
Special Disadvantages:
* Take damage as large creatures
* All personal items, such as clothing, armor, weapons, and food, cost double for half-giant characters. 
** Transportation and lodging, when they're available at all, are also considerably more expensive.
Malleable Alignment
* A half-giant character selects one aspect of their alignment to remain fixed at the time the character is created (either the “lawful/neutral/chaotic” side, or the “good/neutral/evil” side).
* The other aspect is determined at the start of each day of game time.
* The character is bound to that alignment combination until they sleep and wakes again.
* Half-giant psionicists must have a fixed lawful or neutral aspect; they can't be chaotic.
Multiclass Notes:
* Ranger may be substituted for any fighter entry under elves, half-elves, half-giants, halflings, and thri-kreen.
* Gladiator may never be a part of a multiclass combination for demihumans.
