Nasty.However, offensively, what you should do is manifest it and then immediately stop concentrating next round. Boom, instant -4 penalties without a save for an hour.
Hmm, okay. But that suggests that to get the benefits, you have to fail your save in the first round, leaving you dazed; then in subsequent rounds, make your save, keeping the benefits but fighting off dazedness. Is that right?Naw, one will save in the beginning to fight off the ability period. Then you have to make additional ones as you become addicted.
By the way. Animals? Sick. Aberrations? Ewww.
