Any tips for the Jenny o The Woods contract? I hate bosses that regen health...
The trick to beating wraiths:
Before triggering the fight.
Coat your blade in Spectre Oil.
As soon as the fight starts:
Go into the inventory screen.
Take a Tawny Owl potion to boost stamina recovery.
Take a Thunderbolt potion.
Make sure Moon Dust bombs are equipped.
Now back to the fight:
Use Quen immediately and once the wraith approaches cast Yrden.
Stay near the trap and coax the wraith into it. It won't damage it but it will make it become solid so you can hit it.
When you get a chance throw a Moon Dust grenade at the wraith.
Smash it with fast attacks. Keep triggering Quen and Yrden. If you take damage use Swallow, cast Quen and try to recover some health.
I've demolished wraiths a few levels above me using this method so it definitely works.
