I'm newbie and I wanna make my lvl 150 character a tank.

I wanna be braindead and not die while also being useful. My highest lvl char is 271 and I made it a farmer. I wanna make my lvl 154 char a tank (I have 210 skill points right now). Is it possible to turn it into a tank without expensive equipment so I can slowly learn how to tank? (I know I need to level up my characters to max but leveling it up right now feels tiring and boring so I'm taking a break to just enjoy the game by doing stuff I like)
