Sounds like you have low audacity
Might want to bring your aud up. Try messing with your traits, go for some crit defense, and mitigations, hey increase your survivability. I don't have a spider, but a Blackarrow, I have been able to defeat low ranked (1-4) wardens fairly easily since rank 6 when I got damage increasing stances. I have heard that weavers have some kind of damage reflect skill, I don't know what rank it comes at, but try that.
Best of luck.
