How can we Make Ninjas very very Tanky?

[Haeven]

Hey everyone! I'm a sprout and a Ninja. I love the Ninja and doing damage. However, I die or run away a lot. Haha!

Is there a way to make a Ninjas so tanky, they never die or are unkillable (or at least as tanky as an average tank)? Do you know of strategies with your abilities or gear? For example, how do I increase dodge chance?

It can be a discussion; lots of people can benefit from each other. For example, talking about gear may benefit all DPS. But strategies using abilities are also good.

Thank you for your help!
