Hi everyone please find below what I believe to be the optimal midscreen combos for Dark Fate Terminator, this is only after 2/3 days of labbing so there may be some slight improvements but I think this forms the baseline for what you should aim for when comboing in this variation.
I am still working on optimising corner combos and the running man cancel in the corner opens up so many possibilities and will take more investigation.
There are some combo paths that I haven't listed such a Midscreen 1 Bar (No KB, Fatal Blow (No Damage Buffs), because it doesn't net more damage for the additional bar etc.
