How exactly does holy symbol work now (Post bb)

So its not actually 150%?

So u can have a lvl 80 priest training and skeles, as long as u are within skeles lvl u will get the hs effect? And the hs effect will count for those who cannot leech?

If you have a level 80 priest hs'ing you at skeles, you will get 10% extra exp per kill.
If you have a level 150 bishop hs'ing you at skeles, you will get about 20% extra exp per kill, and the bishop will get about 30% of what a normal kill is worth, so total exp per kill is 150% but it's not all going to you.
