[PF]Tenacious Guardian question.

[isildur]

Tenacious Guardian (Ex)

At 3rd level, a bodyguard can always act in a surprise round (though it remains flat-footed until it acts). As long as its master is adjacent, a bodyguard remains conscious (though it becomes staggered) when its hit points fall below 0. While below 0 hit points, the bodyguard loses 1 hit point per round but gains a +2 morale bonus on attack rolls, saving throws, and skill checks, dying only if its hit points reach a negative total equal to its Constitution score plus its master's class level.

This ability replaces evasion.

what's the meaning of 'dying only if its hit points reach a negative total equal to its Constitution score plus its master's class level.'?

it's just typo of dies?

"Dying" is acceptable, though replacing that word with "and it dies" would be slightly more appropriate.

I fail to see the problem here.

A present participle should not be used to describe an instantaneous event, such as the conditions under which an individual dies immediately. They're only dying while between 0 HP and the described value. Once they hit that value, they're no longer dying - they're flat out dead.

However, that's probably more a common misuse than a typographical error.

Edit: Wait, that's not the right term. Blah. I'm sure someone else can manage it better.
