Guild Wars 2

So I was soloing TA path up today and I was able to make it up to the Fyonna “countess of spiders” but I am having an incredibly difficult time beating her (I’m on my main a with zerk engineer) here is my build mostly zerk I know that I should use a different runeset such as scholar or ranger, and also a slaying signet. but please any suggestions other than the ones I’ve already noted would be much appreciated.

I only soloed the path on my mesmer before so I dunno what I am about to say will be much help.

On her sylvari form, get as much projectile reflects as you can (Elixir U toolbelt, Shield skills). Maybe can try chilling with nades. On her spider form, I will dodge her lunges and pop toolkit 4 if i run out of endurance.

Edit: Have you tried LoS’ing her back and forth around the corner of the tunnel entrance? I havent personally tried it before but you might be able to stall her while your cds recharge.

i tried the elixir U thrown, the shield 4 skill but yeah was still having trouble had not tried the LoS with the corner though, I will have to try that the next time I go in thank you. Any other suggestions are welcome too.
