30% damage reduction for 6 out of 7 turns is amazing but we will probably never get that monster in the US version. We should get Phoenix Rider who has 30% for 4 out of 6 turns damage reduction and double 2 prongs. Good for my future Awoken Shiva team.
Edit. They both put Awoken Isis to shame with her weak 15%.
