I like the zelot carrer of Saltzpyre it is the second best after Whc.
For chaos Wastes there must be a "rework"or some changes.
While i think it is good getting healed between the missions. it just sucks to get low enough for your stacks on ever new mission.
i would suggest somtinkt like an addion to the lvl 5 talents of him or a baseline perk like:
Only wounds can be healed with healing items bt they no longer restore “green” health and maybe a higher rate of temphp, although he didn’t need more means to genereate more tmphp
