Effect: Target can levitate 1 space each turn.
Does the spellcaster need to maintain concentration each turn or must they make a spellcaster roll each turn to move 1 space. I'm thinking it is the simpler former.
As long as the spellcaster is concentrating he is able to move the target (or himself) using transport.
Note that some GM's may ask the caster to make a spellcaster skill check if he wishes to perform other actions on his turn while using transport such as casting another spell, shooting a bow, etc.
