- Travel to sub-mission Shadow of the Sacred Mountain (part 3).
- Jump up on the rock pillars to your right and grab the dragon’s cure powder.
- Jump down to the flag and travel to the same location.
- Pick up another powder and keep doing until you have 10 of them – if you have fast loading times it should take you just a couple of minutes.
Now you have 10 surprisingly powerful regen items that should boost your healing capabilities by a lot. Equip them to your quick slot and use one and start face tanking bosses. Repeat until all bosses are dead.
