First, this site is great, the guides have always been helpful, and until today Calcs like Max Hit have always seemed to accurate. Here's what was going on Slayer assignment: Black Demons. I let the Calc come up with my Strength Bonus -- 98, this was what RS came up with I was wearing a Slayer Helm, Checked it in the Calc as well as Slayer Monster. Selected Super Strength Potion Selected Piety Calc said Max Hit of 424, I got 433, Several times, right after drinking a Super Strength Potion. I didnt check it without Piety, Like I said the calc has always been right before but this is the first time I used it with Prayer. No big deal, actually was a pleasant surprise to see a higher than expected Max hit
