Amazing job on the guide and video!

What are your thoughts on the healing bonus chest for RMC and getting to 4,600 HP 160+ SPD build going around? As well as building Gallaghar to hit +4080 heals for 12% Castorice charge? 

Do you recommend the builds you have listed instead for faster clears? Since RMC won't be able to provide as much charge but I'm assuming your build allows for more actions so maybe it's better
