Start by trying to get some darklight, but WP should be a decent place too, just can't speed run the place. Fill in the gaps were you can, and go for DL soon as you can, Once you've got some of that and you're upwards of 5500 or so HP should be okay to start working on the relic. I myself wasn't comfortable in Titan HM until I had more than 5700 or so HP, and then ate food to get as close to 6k as possible. Table Flips hit for 3200+ without a cooldown.
