The Corpse Companion supernatural ability of the Undead Lord Cleric archetype says this: "She can use this ability to create a variant skeleton such as a bloody or burning skeleton, but its Hit Dice cannot exceed half her cleric level."
1) Do you round up or down to determine half your cleric level? Is the minimum 1?
2) Can this ritual be used to combine any number of compatible skeleton variants? If so, why wouldn't you?
3) Are there no material components for this ritual?
4) Can this ritual be used to create a skeletal champion? Skeletal warrior?
5) How is this class ability anything but a weakened animate dead spell?
Thanks
