what does the phrase at the end mean?
quoted from restricted 2010 player's guide:

BLUE LANTERN
Cost: 5
Light: Continual. Characters within 4 squares of this object that can use Barrier or Telekinesis modify their range values by +2 and can use Telekinesis for 10 squares instead of 8 (for all limitations of Telekinesis) if they can already use Telekinesis.

Exactly what it says: if they can use TK, then they get the boost to TK range; if they can't already use TK, this object doesn't magically allow them to suddenly use TK.

If that line wasn't there, then it would imply that figures within range of the object could use TK

oh ok! thanks!
