I believe my attack was misconstrued: The object of the Psychic bubble wasn't to create a shield and try and stop the blasts, it was to set up an invisible bubble that was close enough to make the exploding seeds backfire and injure Yariza.

Also, how does a Seed Bomb only use up 2 points of energy? far as I remember, it's a pretty strong attack. Especially if about half of it is still enough to do 7 damage to its target.
