So I've been playing around with Earth as main for the last few days and trying different talent setups. One of the last ones I tried was using "Earth Style: Petryfing Jutsu" (shield) as the standard attack, and "Earth Style: Boulder Jutsu" (extra move for random member of the team each round) as one of the passive talents. The Bug (?) I noticed was when he buffs himself, the shield only adds half as much as it should per move. What I mean by that is, when my main does a single move, he shields two people for 1,200 each. However, when he gets buffed, he shields for 600, twice. So nothing is gained from the "buff" for the main.
I assume this is a bug, since I've also tested the shield move/skill with running the Myestery move "Earth Style: Super Lightened Boulder Jutsu" (adds a second standard attack for the whole team) and it does allow my main to shield two people on the team for 1,200 twice (total of 2,400) in the same round.

Anyways, I just wanted to confrim if this is a bug or not

Thanks
