Hi guys, quick rules question. Please help me out!
Can a rogue using a vanishing wayfinder sneak attack from invisibility? Can they full attack from invisibility?
Vanishing wayfinder:
In addition to the usual functions of a wayfinder (including the ability to create light), as a standard action the holder of a vanishing wayfinder can press a hidden catch to become invisible (as the spell invisibility) for as long as she concentrates, up to a maximum duration of 5 minutes per day. These minutes need not be consecutive, but each activation counts as a minimum use of 1 minute, even if the user becomes visible because of an attack action or some other event before that minute is up.
Concentration rules:
Concentration
The spell lasts as long as you concentrate on it. Concentrating to maintain a spell is a standard action that does not provoke attacks of opportunity. Anything that could break your concentration when casting a spell can also break your concentration while you're maintaining one, causing the spell to end. See concentration.
You can't cast a spell while concentrating on another one. Some spells last for a short time after you cease concentrating.
So, does the vanishing wayfinder require concentration (a standard action each round) to keep invisibility? I think yes. Then, one cannot attack when using the wayfinder. But a little later on, it says that a standard attack will break the invisibilty. But you lose the invisibility if you don't maintain it with a standard action.
My fundamental question: CAn a rogue sneak attack while using this item? Can they make a full attack action, the round after last concentrating, and attack from invisibility? What do you think?
Yes, the Rogue can Sneak Attack from invisibility. He ceases to Concentrate the moment the first attack is made, which is when the invisibility ends.
