I loaded up the training game and and it's possible for even me to defeat Trinexx that way, but it's challenging.
#What are the odds of Trinexx, master sword, no bottles? Pretty low, right?

pretty unlikely, if you have hammer it's less bad.

hammer trinexx is worth learning for this case, since in standard settings you will always have it
(tip: stand closer than you think you should for the first ice rod shot and hammer hit)

The logic definitely let's you have some magic extension for the master sword fight, I think half magic might be enough though so it's possible but at the very least you would have more than a single magic bar

I mean, it's possible with MS and 8 rod shots (you can get 3 swings in per rod shot without doing anything special), but kinda rough. hammer lets you do it in 4 optimally and 6 suboptimally

Now for a fighter sword Trinexx you're required to be able to get at least four bars of magic

FS Trinexx assumes you just rod spam them in phase 1 (yes, you can do this)
but, again, not possible in default-like settings, and very unlikely even in the more exotic settings

FS Trinexx assumes you just rod spam them in phase 1 (yes, you can do this)
And that's got to be the easy part because phase 2 with fighter sword spins sounds insane

Lol, I forgot about the hammer being required in default settings. I've done the hammer strats before successfully, though it's not super fast.
