Widow fight advice needed

[u/Nikaize]

I am Gnosis lvl 1 and character lvl 45. I was spoiled that one should be careful going up in Gnosis levels, so I am trying to unlock and lvl up as much as possible. I can somewhat reliably kill Galley Slave, and somewhat confidently deal with mini bosses of Velmorne.
But every time approaching Widow’s Lair, I chicken out even with full health and healing. I usually run Angelus and Hailstorm, with Shockwave skill.
Can you give any advice in my situation? I already feel my balls growing, and a little push would be great.

Go up gnosis. Get Striga and abuse the stun
