Glad to see a video from you :junglejane: please upload some more, would love to see your fm do mushin floors 9-15.
Things to note on, i seen that you weren't using forc blast every time ember stacked up to 5 like i know we as fm's have other skills that throw on burn but essentially 1 will always be a must use type of thing if your running a burn build to keep it up at all times. Oh also don't know if you have hm lmb but it is very worth it stage 2 tier 5 if you have burn soul and are applying burn, lmb starts to crit for 7-8k which i presume is better then the ice soul (unless your running a freeze build) and your beam will crit for 11-12k so you would increase dps if you just did that.
