So I am reading
http://battlecollege.wikispaces.com/mkiiSaeryn this, specificly:
"The Feat allows you to fly some Angelii and ignore free strikes
but remember infantry under her command aren't immune, and the next turn the enemy can still fire at your beasts just not attack them in melee."
"but remember infantry under her command aren't immune" Um.. why not? I guess they are meaning not immune to free strikes... but free strikes is a melee attack (page 51 in Hordes mkII, "The model makes one normal melee attack"), so... her feat should make things immune to free strikes. And of course sitting with Saeryns card and reading "by melee attacks"
Or is there an errata that is around? Can't find any.
