How to beat single assassin boss as ranger alone?

Hello, I am trying to kill one single assassin boss. Tried to trap him, spike him - didn't help. Problem is, he's doing a lot of damage and throw dirt lasts just 10-20seconds. Any ideas how to kill him? I was thinking about shadowsong+spike, but I am not sure I could spike him until shadowsong ends.

oath shot keep throw dirt on him at all times

Thanks for posting. Tried it, but although I have in expertise 10 points he killed me in about half minute. second time, I tried oath+traps, it was better but still he could kill me, he was running out of traps so he regenerated quickly [shadow refuge]. I think neither spike and neither traps will help.

Boss I am trying to defeat using these skills:
Golden Phoenix Strike
Way of the Empty Palm {E}
Repeating Strike
Shadow Refuge
Unsuspecting Strike

Did you try whirling defense and or dryders defense? Him missing unsuspecting blow will surely mess things up.

I'd also be curious to try it as a thumper. I know it's far from the same thing, but my hammer warrior tears through my guildies' assassins in 1v1. I would go with Devastating hammer for the less adrenaline, then get belly flop in for the blind. Mighty blow, then heavy blow followed by crushing blow.

Another key would be using degen or an interrupt to nix his shadow refuge. Did you spike with Punishing shot and savage shot, or something else? If you could take an interrupt build (or even half of one, since you can predict when AI will use certain skills), and take down shadow refuge, you should be in great shape.

Finally, if you happen to be R/Me, how bout using shame to eliminate shadow refuge?

Basically, posting a secondary would help, but the 2 keys I gleaned from your first post is you need to either avoid attacks or self heal more, and then also try to prevent him from using his heal.

Edit: Just realized you were R/Rt..... so how bout Shadowsong (blind), Dissonance (interrupt), and the one that makes spirit attacks do more damage (sorry, forget the name).

Ok, just figured out a build as R/Me. Put empathy and throw dirt at him. Refresh it with oath shot, activate stances for sure - lighting reflexes or whirling. If energy needed energy tap. Troll for self healing. Repeatedly doing those things killed him! Thanks everyone for posting ideas!

Congrat's!! Can I ask which boss, and why you wanted to solo him? Is it for a green?

Sure. It's a challenge, so I wanted to kill him solo. He dropped nice daggers in second try, so greens were one of the reasons maybe too

I found him. In pongmei valley east of maatu keep. I'm having trouble getting into the rythym to recast things. It may be that it's 2:30 am and I didn't get much sleep last night. I'll try again tomorrow when I'm not tired. Although, I do have a final tomorrow, so maybe not. I'll either be studying or too burned out to play anything. Way to go Anet, release factions just before college finals.

How about trying Oath Shot, Apply Poison / Nest of Vipers, Hunters Shot, Throw Dirt, Dust Trap, Dryders Defenses, Lightning Reflexes, Troll Ungent.

Basically try laying as many traps to start with, Nest of Vipers / Apply Poison to poison the boss, Hunters Shot while he is running towards you (or away from the traps). Blind him with throw dirt and dust trap so he cant hit you and Dryders / Lightning for when he isnt blind or your trying to lay the traps. Oath Shot to recharge skills.

The palm strike counts as an offhand attack, but doesn't need a lead attack to activate it.

Try BHE (Dazed works great - alot of the Assa´s skills are spell-based)
Throw Dirt
Apply Poison
Conjure Phantasm
Tigers Fury
Serpents Quickness
