I have several questions.
"Unique Ability: Experienced Dreamer - Any Phase: Luke gains 1 Clue token each time he enters an Other World area or is Lost in Time and Space. "
1. When does Luke get his clue concerning lost in space? When he enters, meaning he'll get two clues in one turn or while is in it, on the next turn, which for everyone else is skipped? or both? It won't usually make a difference but sometimes it might.
2. Does anyone play that Luke can go right back into an Other World when he returns from an Other World. Or does he have to move out and move back (which can be quite difficult being both slow and somewhat clumsy). The lowest he can get his sneak down is 2 to move out and back.
3. General impression of Luke. Do you like to play him, hate to play him or he's just another average oh hum investigator.
4. It looks like he's wearing a bathrobe but what's up with the mask?
5. Back story. Per Arkhamhorrorwiki, he doesn't have a gate but but rather a mystic puzzle box.
