Does its effects stack with TP skills? I'm using the rental accessories from it, and that gives 3 of the set which should give Inferno Road 2 extra pillars. I also have the Inferno Road TP skill, which also gives +2 pillars. Yet I only seem to get 3? If they don't stack that's fine, I can save TP on Mastery skills. I just want to know if this is normal or if I'm just not seeing it.
