So let me get this straight, Immediate and Swift actions both of which consume more time, energy and effort than a free action, only the Immediate action can be performed out of turn, with speech being the exception? Barbarian plummeting to his doom screams, "Someone please save me! I am surely going to die unless some one helps me! Will no one heed my cries?" allowable as a free action-(no more than a few sentences)yet cannot enter rage instead ,something that consumes no time at all according to RaW? When can common sense be used in a round? Is it a standard or full round action? My point being this, in no place does it state that speech is the only exception to the rule(that I could find) and is only one of four actions listed under Free Actions descriptor. Why can't something that takes no time at all be allowed anytime? I understand allowing for initiative i.e. (has yet to act at all) and being surprised but beyond that...
P.S. Just read contradiction in book under Actions types, "Free Actions consume very small amount of time and effort," while under Free Actions title it states, "free actions don't take any time at all, yet there may be a limit to the number of free actions you can perform in a turn." What's up with this?
