Veteran abilities for a Spider I'm playing in a game currently as a Spider.  Mostly my guy ends up being the one to serve time to reduce our team's heat. I've been mostly advancing my playbook with my experience and currently have Demonic Attendant and the one from Leech (I think)  that gives two stash every downtime.  

What would be a good third,  and final,  ability from another playbook to round out my character?  

If it matters,  my team is a cult that's big on human sacrifice.  I've currently earned two guard payoffs and allied ability (the hagfish one that disposes bodies and allows a 1d6 reduction in heat) from going to prison.
