Kalani's Landing reaction has the targeting in the cost section (before the colon).
If I target one of my own personalities is he performing the action?
Kalani's Landing reaction and performing
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
No.
Glossary- Perform:
Perform A Personality or Follower is performing an action if its controller is the player taking the action (or, if the Personality or Follower is out of play, if its owner is the player taking the action), and any of these things is true: •The action is from an ability on the Personality or Follower. •The action is from an ability on an Item or Spell in the Personality’s unit. EXCEPTION: Actions on an Item or Spell that attach the Item or Spell itself to a Personality are performed by the Personality even if the attachment card is not yet in the Personality's unit. •The Personality or Follower is chosen or designated as a performer in the action's constraints block, using the word "performing."
