Thanks for the update Grekumah. I do appreciate your continued communication about this subject. That being said, the points you've provided are contradicting and are not new information. It seems like you're giving our own proven facts back to us and claiming that these are additional details from the development team.
1. This has been proven false by players and point #4 contradicts this.
2. This is irrelevant in relation to the update note since it's impossible to reach 575 summoning magic skill.
3. The Caller's Horn +1/+2 has always had this effect and the update made no changes to that.
4. This was actually found by the player Papesse and avoids the issue of what changes where made to the other Avatar's Favars that was claimed by point #1
