feedback1b WI: 守墓石像's statue and flight are 失衡免疫; 喷气人 lands unblockable

PRTS 守墓石像 / 愤怒的守墓石像: the statue is unblockable, rooted, 失衡免疫 and
immune to 浮空; the reborn flyer is 失衡免疫 (not a 静态刚体, so a persistent
noDisplace buff). PRTS 喷气人: 1.5 s at -90 % speed after take-off, then
1.333 s unblockable at -90 % speed after landing.
