Darksky needs to be updated I think, was wondering why it didn't match! But it works according to this ann:

Not sure it is scaling though? Giving 1300 on 0% and 1200 on 25 %, shouldn't it be either 1000+75% of 300 or just 75% of the 1300?

If owner has darkness principle it increases both attack and defence by the value of this principle, otherwise it increases attack double the value of the principle but lowers defence by same ammount.
0%
25%
100%
Claw2, Claw3, Sunshine seem fine. BD2+3 seem fine after taking into account stats (30494 attack 5550 initiative) and sword shade 3 stats - I suck at maths though.
