New darklight is kind of lacking... It didn't need buffed to begin with so I'm not sure why that was a reward, but it hits as good as an addy sword on all the "new" demons other than hellhounds so
It's not the end that I fear with each breath, it's life that scares me to death
I know it's 10 earned from skilling before you can't claim more... I don't believe keys earned from quests/challenges have a cap? Or if they do it's much higher than 10
