Can someone give me a heist build for my Templar?

Tldr: I need a build for my templar that I can heist with.

I am currently playing srs guardian and have my full atlas unlocked. I prefer to play heist but I'm having some issues with my build. I sometimes get stuck between mobs and die (shield charge and frostblink). I would like to run only heists for some time and do nothing else. So I would have no problem changing everything. Does anyone have an idea how I can optimize a templar for heist? Are there any skills/flasks that I absolutely need? I have about 50 div budget but would prefer to spend a little less. Thanks for the help
