God Stat
God Stat is a slang term for a character stat with a particularly unbalanced effect compared to the rest. Its opposite is a dump stat. God stats can be created by a Gamemaster or be endemic to the system. In combat-related games with point-based character generation, for example Inquisitor (a 40k RPG and skirmish-level wargame), it is often a stat that governs the number of attacks or actions-per-round the character is allowed (in this case, Speed, a stat derived from Initiative).
Dexterity is the most common God Stat, often allowing one to hit more, be hit less, and move faster.
