Another Eden - Astral Archive Book of Geo Anguirus Challenge (Main DPS: Yakumo) 

Toova's prayer = Active Link to Yakumo = Shade type add-on attack (just 80% damage) after each Yakumo's attacking move and that link also consumed the elemental break shade from Toova (Ringing Night) = less damage from Yakumo's Deletion. For more info and explanation (Yakumo's Deletion= 5250% x5 move): -with 3 shade break and without prayers from Toova (double damage x3 move and then normal damage x2 move)= (5250% x 2 x 3 ) + (5250% x2) = 42.000% total damage -with prayer/link and shade break from Toova (link consume break also) = 5250% x 2 in first move then the link 80% x2 from the first move then 5250% x 2 in second move, no elemental break remain, then 3 other move are normal damage 5250% x3 then 4 link move are normal damage 80% x 4= 37.230% total damage Hopefully my explanation can answer Your question. You can try it by Your self to understand more about My explanation (Try to compare damage with/without Toova's prayer). Anyway thanks for comment, 😁
