What kind of effect do people think the grails give per one used? As its a max 100 I'm assuming 1 = 1% increase or something like that?
Just thinking due to being the only one in my union I'm having to solo this so don't have tons of grails to throw about so is it even worth throwing away say 5-7 into 4 stats each day or would it be better to save them for nearer the end then just use them all in the last few days to super-power through late level experts or ultimates when they become too difficult to handle without increases.
