Some alternative mods:

[Blood Rush] instead of [Sacrificial Steel] for more overall crit chance but needing to build to full combo to achieve it.

Regular [Organ Shatter] instead of the Amalgam version for 5% more crit damage at the cost of the heavy attack wind up speed. It's better to go with Amalgam, but regular is there if you don't have the Amalgam version or if you don't want to use a forma.

Range mod/[Reflex Coil] instead of [Gladiator Might].
