First I'll list why it's strong, and afterwards I'll go through some of the drawbacks: This is a good build for combat, though it is relatively expensive in ways that may not be obvious from the specs. It works mostly as described, though it requires substantial investment, is relatively risky, and is not necessarily as devastating as that thread suggests Is it really just that? The thing that all game masters should be prepare to handle?
The only explanation I found was on a forum topic about making the greatest supernatural fighter:
The so-called Lasombra Death Machine (Yeah I know there is one more word, but no I will not write it). I found only one build that always returned on the table, with only a few things explaining it: After I looked on some D&D multiclass builds that could break my games (and gave me ideas for bosses), I searched some builds for Vampire: the Masquerade. I'm a DM for D&D and Vampire the Masquerade.
