Also, what sourcebooks can I look at to get descriptions of Traits beyond 5 Dots? For example, Meneleus has something like 8 Dots of Strength, but I got no reference for how strong that actually is, aside from it being some degree higher than the peak human strength of Dot 5
Going by what we saw during Week of Nightmares, this seems about right, as 4th generation vampires can put somewhat of a fight against their 3rd gen masters (just that it usually doesn't go well for the 4th gen unless the 3rd gen allows it to happen or something is seriously wrong).
In the case of the Week of Nightmares, the Ante in question is starving for blood and ganged up on the second it woke up.
