The relationship between favor and valkrie (Possible spoiler)

[Pentagruel]

I have been using a valkrie, and have in general really liked this summons, but I cant seem to find the formula for the number of favor needed to get 3 attacks/ 4attacks from the valkrie. I know that you need something around 450 or so favor for 3, but it seems like one needs around 650 for 4. I am wondering if people know more closely, so that I know how many times i have to die to get enough swings for me to have my valkrie for all my forest fights. Thanks.

Since you are already on the road of Experimentation, why do ye not continue on it, die a few more times and come up with the formula yerself? 'Twould be a much more interesting way than to have the answer just given to ye. The spirit of this game is to find the answers for oneself, asking for hints when one become completely stymied.

I'm going to agree with Shiqra. You seem to know what you're doing though, and I feel like you're really on the right track.

I just got a Valkryie out of curiosity, and I have different than what you do, and yet the summons is quite good. QUITE good. So there are other variables in the formula it seems. Or the cut off points are different. At any rate I am enjoying the experimentation. I have to agree with the two previous posters - keep playing with it. That is what i am going to do!
