Blessed thistle trait discovery question

kenly18

I've discovered every trait for all other plants, except this one. Blessed thistle.
Traits.
1. Restore stamina
2. Unknown
3. Ravage health
4. Speed

Can't find anywhere online how to discover the second trait. Any help would be great.

The trait is "increase weapon power". The other reagents with this trait is dragonthorn and stinkhorn, but both of those have other traits shared with blessed thistle. Try making a potion with dragonthorn and one with stinkhorn, and if that doesn't work try making a potion with blessed thistle, dragonthorn and scrib jelly, it should work.

Edit: just checked, blessed thistle and dragonthorn works
