umm ... just save 200 runes. Normaly it takes like 50-100 purifies to get a good ones and I mean for init only. With 200 purifies I just got 3x yellow (over 81%) and over 10x purple that I deleted unless I got purple or yellow init. In the end with 200 purifies I got 2 items with purple init, one item with yellow init and some purple/yellow secondary satts like control etc. Not a rigged thingie. Totaly RNG. Only some things are rigged. Like for example slto machine where only 1 person daily per server can get tsunade and so on. This is definitely not. Once I got even 2 yellow at once. useless ones like injury and control but better than nothing.
