Is it worth it to trade Escalating Pursuit for Transmutation Cycle for Sodam? I'm a Hu/Et, and i already have the optimized endgame gear (Klauz sword with Augment Will 2, Precision Will 2, Precision Will 2, Escalating Pursuit, Flashguard Unleashed, Grand Might, Phrase Decay and Guardian Soul; each Klauz unit have almost 300 atk). 

However, despite consistently landing Blaze Parry on Sodam, I can barely beat it below 10 minutes on depth 50. And with given time of 15 minutes and massive jumps on later depths (especially 100), I doubt that I can clear them in time.

Since Sodam keep changing elements, is it a good idea to trade S4: Escalating Pursuit for S4: Transmutation Cycle to change our weapon element for our advantage? Also, I'm currently using critical ring. Is it viable to temporary trade it for elemental guard rings to support this strategy?
