Rajsa main thing is the 5stp with all the other positive stats.

the following is a very loose example of why.

5stp gives roughly .5% extra tp per hit meaning if you were going ot get 19 tp a hit you actually gain 19.5 so you would go
*you dont see the .5* hit 1 19% hit 2 39% hit 3 58% 78% etc
without the ring you would go 19 38 57 76 , you see how big of an effect just that ring alone has

WARNING the above math is not 100% accurate its just to get the other person to understand what stp does.
