I want to be good at healing. so that I can keep the group up by my own but also have something unique about the char... as always played a cleric.. just want something a bit different. 
I did not realise channel energys from different places didn't stack.. so thanks for that info...
I never knew the bracers of merciful knight excisted... I have been trying to find an item/feat like those!
you say based on the build above? is that the 4 pally / 6 oracle? or the 4 pally / 3 oracle /3 vindicator? 
but having lay on hands at 8th level and channel as a 9th level cleric is very nice. its the sort of thing I was trying to play around to achive. ofc its not as strong as pure classes. but its strong enough and be a unique char! so thanks a lot. 
I have actually been looking at the dual curse archetype. I love the rerolls. very handy. but I am not a fan of tongues... as I like to be able to talk saying minor stuff like. I wont be able to heal this turn or something along the lines... so doubt id end up picking tongues... I was looking at haunted and maybe cloudy vision. for RP cases. because most of my healing will be channels / lay on hands myself to keep up with the life link damage... if I cant see you.. then you don't get healed. :P
