It was far more difficult to fight the weaving illusion than Lind expected. His clawed hands may be able to pass through it but the conflict between what his mind told him was real and what his claw actually felt produced a pounding headache.
It was not like when Delenn or Annabelle used formations. The Qi in illusion formations used the elements to reproduce what the user wanted to be projected. Annabelle in particular used water and light Qi to extremely versatile effects that even Delenn had trouble telling the difference.
Lind's Heaven Eyes could see the illusion formations easily but not what was behind them unless his Heaven Touch broke up the flow of Qi. Weaving illusions seemed to be more invasive.
