Combining Thug + Boasting Taunt

[thepuregamer]

So lets say we have a rogue(thug)1/barbarian6 who has boasting taunt.

Thugs get the ability frightening:

Spoiler:

Whenever a thug successfully uses Intimidate to demoralize a creature, the duration of the shaken condition is increased by 1 round. In addition, if the target is shaken for 4 or more rounds, the thug can instead decide to make the target frightened for 1 round.

and boasting taunt says:

Spoiler:

While raging, the barbarian can incite a creature to attack her by making an Intimidate check to demoralize. If the check succeeds, the target is also shaken as long as the barbarian is visible and raging or until it makes a melee attack against the barbarian. The barbarian receives a +2 circumstance bonus on this check for every alcoholic drink she has consumed during this rage. This is a language-dependent mind-affecting effect, and it relies on audible components. The barbarian must be at least 6th level to select this power.

So when you demoralize an enemy, anytime you succeed, your enemy becomes shaken until they hit you or cannot see you anymore. Is that the same as saying the duration is unlimited and the condition is canceled by no longer being able to see the barbarian or hitting the barbarian.

If it were unlimited, then using the thug ability, you could exchange it for them being frightened for 1 round.

I am not necessarily interested in using this, but thought I would see what other people thought about it.

The target is not shaken for an unlimited amount of time, only for an undetermined amount of time.

Frightening could have been written: "In addition, if you beat the DC to demoralize by 10, the thug can instead choose to make the target frightened for 1 round", since that is what is required in order to get "4 or more rounds" (including the +1 bonus from the ability itself).

Because the boasting taunt doesn't have a set length of effect, you can't be sure that it will last 4 rounds. In that case I would not allow you to frighten them. I would, however, allow the shaken effect to persist for 1 round after the boasting taunt ends.

I've been using it (Thug - Frighetening), with the Enforcer Feat and plan on using it once I get 2 levels of Cavalier with Braggart/Dazzling Display. Being able to make things Frightened for 1 round has provided a good amount of crowd control since our party doesn't have a wizard or sorcerer.

Also, we have been playing it that anything over 4 rounds of shaken goes away when choosing to make them frightened. But my character isn't doing the barbarian thing. *shrug*
