I'm Unsure What To Do With My Character.

Im a level 78 assassin that dies trying to grind in normal grind spots as my defence is actual garbage. I don't know what to do now other than do quests as grinding just gets me killed and I don't know if I'm doing something wrong.

My gear is a level 70 Chakram (Dagger)
Helmet of the legends.
Cage of bones (when im grinding I switch to jingling jester).
Evening Primrose,
and Stalagmites.

My SP are 27/67/0/50/0. Strength, dexterity, intelligence, defence, and agility respectively.

All my accessories are xp bonus and loot bonus.

Should I get better gear or should I just keep doing as many quests as I can to level up. (Literally any feedback is useful as I'm completely lost)
And how do I link my in game account to my forums one?
Thanks!

I'm kinda new so I don't know if this will help but intelligence is really good.

All tips I've seen say to level intelligense since speels do a lot of damage
