alf2 - current state: fire/ice affinity exception

[YinYin]

in alf2 i have given firen, freeze and firzen an affinity or immunity to ice and fire attacks: [link]
this works on almost every attack except for two:
the inferno and the ice sword
pretty unspectacular :D

how it normally works and why these two cause problems (Click to View)

how it works:
every fire and ice attack has a seperate itr written above the original one
this one has the same dimensions, but no effect and different injury and fall values
it is also located at a certain distance on the y axis below the ground

the character that should be affected by this new itr has a bdy at the same height below the ground

itrs in a frame are acting from top to bottom, if the first one already hit the second one may not be carried out anymore
so it is pretty simple to give the first one a different effect, damage level and anything else you like

the problem with firens inferno is that these frames would generally allow self hits due to their state
but the fire effect used there is special so that this doesn't happen, however any itr that does not have this fire effect will not only hit teammates aswell (other firens/firzens) but mostly hit firen himself when he walks into the flames
this is something i cannot put up with

the problem with the ice sword is that weapons use special damage settings in their itrs from the header if the wpoint inside the character specifies any attacking
this however only allows for one kind of itr to be carried out inside an on_hand frame when attacking

the question is:
should i keep these exceptions or search for a way to enable immunity on those too?

if i keep them i will probably add some visual effects to these two moves when they hit the corresponding character to underline the fact that these are too powerful for them to handle

if you want me to keep searching for a solution i will probably need your help and ideas on how this could still be done
i think it is not possible with data changing only and will require hex editing - but i am open for you to prove me wrong
