This is the situation: A drow enters the space of an invisible and hidden wayang ninja without detecting him. The ninja has the option of striking the drow with an attack of opportunity but, reasoning that they'll do more damage with two weapon fighting and a full attack later, opts not to.
If the drow had continued his movement this wouldn't be a question but the drow finishes his movement in the same square as the wayang.
RAW says that you can't occupy the same square. Core p194: "Accidentally Ending Movement in an Illegal Space:
Sometimes a character ends its movement while moving through a space where it’s not allowed to stop. When that happens, put your miniature in the last legal position you occupied, or the closest legal position, if there’s a legal position that’s closer."
The wayang ninja had three options:
1) Maintain invisibility and move out of his way;
2) Maintain invisibility and block him by standing still (not an attack on his part so invisibility is unaffected);
3) Make an attack of opportunity and lose invisibility.
The wayang ninja chose to actively avoid the drow and the drow who was unaware of the wayang ninja.
The GM ruled that the wayang ninja would move to the nearest unoccupied square for free but the option of squeezing into the same square was bandied around.
How would you rule on this?
