Maybe it is just me, or the RNG is being friendly, but the Guardians Tame (spell) might be slightly malfunctioning. It succeeds far to often. For example: Taming a dragon succeeds in about 70% of the cases even while they are supposed to resist it with 80%.
During the dev stream I mentioned this in the chat, but Kristin did not read the complete description of the problem and therefor Scott did not really got the problem. However he stated that maybe Mastery levels were influencing the success rate. And i did obtain them when the Tame spell was cast by an unit that was wearing multiple rings of mastery. So there might be something there.
A clan of dragons.
A sleuth of bears (including Ben).
A cluster of spiders (including Bill).
