As the title says, I am just curious what the lowest * titan you have taken down that gave out a 4* ascension mat (not including rare titans). My alliance usually stays around 7-9* titans but was interested to know 
My records show a Tabard and a Telescope from 7*. Not sure if they were from rare.
Correction, those would have been tier 7 score.
I remember getting 4* mats from 5* titans every once in a while. I was new back then so my score was B.
Rare 5* titans never dropped that many mats if I remember correctly.
I got a 4* mat from an escaped titan once, wish I screenshot it.
