I have researched current pleiads.xml in official package based on 0.221.

"invincibility" : it is "hit but no damage" for enemy. "no hit" is included in posted code.
"shoot upto 2 bullets" : not work. Fixed version is in posted code as "max bullets up" .
"skip stage" : not work in 2 stage or later. Is it correct?
"shield" : I have no idea because pleiads seems not to have any "shield" factor.
