I'm not sure I'm following; I've played the game dozens of times but always used scrolls - are you saying that it can be used as a regular discipline?
Sure - Walk the Abyss is a common discipline (available for every vampire in Redemption). To get it you need a minimum of 25 points of Intelligence and 25 points of Wits, plus you have to train yourself in all disciplines from Common section (at least one level of every discipline). The last one (7th in a row) is Walk the Abyss. It does cost 10 blood to cast, but it's still much cheaper than scrolls (blood is basically walking the streets, right? ;-) ).
That's why I encourage other people to take a look at the Vampire The Masquerade Redemption site at GameBanshee
. There you can find description of all the disciplines, along with their requirements, not to mention the equipment database and a complete walkthrough.
Interesting; guess I never really mastered the interface. Thanks. Guess I'll have to dust off this game yet again. I'm betting I didn't train in one so stopped the progression. I've never seen walk the abyss in the common traits area.
