Energise Strikes Stacking

[siegfriedliner]

This is probably just me failing to see a clause, but as far as I can tell at the moment there is nothing stopping you energising your strikes multiple times within a minute and whilst I imagine it probably doesn't stack with itself on the same element their is nothing stopping you mixing up the elements you energise with.

Now doesn't actually seem broken because of how much setting up you would need to really get this chain going in earnest. But it also seems unlike pathfinder 2e to let you stack stuff to your hearts content, so I am guessing I am missing something.

I would say this would be covered under Duplicate Effects.

When you’re affected by the same thing multiple times, only
one instance applies, using the higher level of the effects, or
the newer effect if the two are the same level. For example,
if you were using mage armor and then cast it again, you’d
still benefit from only one casting of that spell. Casting a
spell again on the same target might get you a better
duration or effect if it were cast at a higher level the second
time, but otherwise doing so gives you no advantage.

So even if you were to choose a different damage type, you would still be under the effect of Energize Strikes more than once, meaning only the newest use of the ability would take effect.

Thought I was missing something.

Still a pretty good feat mind you. It's shame vulnerability is so rare otherwise it would be pretty amazing.

It's about as good as weapon specializations. But it scales on weapon's dice and not proficiency, with magus Potency you almost always have the maximum number of dice. And can choose the damage type to exploit vulnerability when there is some.
So it's also good when you use a backup weapon with Magus Potency to pass some resistances (say a silver shortsword) and then add some cold damage on it too.
