If I asked the question, it is because there is no "minimum of 1" in the rule. Now, it may not make much sense to create a Cleric with a Charsma of 5, but if we apply negative modifier to the 3+, it means such a Cleric will not have any Channel energy ability at all, which doesn't make much sense either. So, I'd like to know if the creators of the game really intended to make it impossible to channel energy with a low Charisma or if they meant 3+bonus (so a minimum of 3) times per day.

For special abilities like the Cleric Channel Energy or Domain Powers or the Barbarian rage that can be used a number of times per day + ability modifier, does negative modifiers count? For example, a Cleric can Channel Energy 3+Charisma modifier times per day. If he has a Charisma of 6, can he use it 3 times per day or only 1?

It seems quite obvious to me that negative modifiers shouldn't apply (otherwise a cleric with a Charisma of 5 gets no channel energy at all...), but I can't find it stated anywhere.

Please clarify for me :)
Thanks
