A perfect Blazamut Ryu also wants 100/100/100 IVs (breeding averages the parents with a bonus, so high-IV Blazamut Ryu parents compound) and 4-star condensation — feeding it spare copies raises this Dragon / Fire Pal's stats and every work suitability a full level. Craft-speed and attack souls from the Statue of Power stack on top. The planner routes these passives from pals you own; see how to breed Blazamut Ryu for parent combos.
