Thanks all for help and good brainstorming.
I was thinking of going at least 2 levels of Paladin's Sacred Shield at the beginning and then 5-7 levels of Brawler shield champion and the few extra paladin levels again for more use of Bastion of Good ability. I wanted to make a back liner support/ ranged thrower with possibility to do some melee dmg also...
I try to use my "player" charisma on the inspiration side :P (to boost my other players' motivation and the keen to diplo some encounters instead of killing everyone we face)
Any thoughts?
