What does charisma do in New Vegas?įallout: New Vegas Charisma in New Vegas modifies Barter, Speech and Companion Nerve. In New Vegas it affects "Companion Nerve," which means it affects your companions' health and damage output. In Fallout 3 charisma has the effect of increasing speech check success (independent of speech skill), but since you could just reload a failure it was rather useless. 1 charisma and 100 speech is the exact same as 10 charisma and 100 speech. Like fallout 3, charisma really doesn't affect anything since most checks are based on your barter or speach skill level, not your charisma.
