Shorting out ITRs with Itr Kind 4 and 5.
This is actually mentioned at the end of my first post, but I'm going to give more details and an update on whether to use kind 4 or 5.


As you know, an object may only have a maximum of 20 hit instances with its ITRs.
Each object may only have up to 5 ITRs and 5 BDYs without stability issues.

One useful way to reach this limit is to give an attacker multiple vrest: -1 ITRs, while the victim should have multiple BDYs.
Each ITR should overlap as many of the multiple BDYs as possible.
So you could use 4 ITRs that overlap 5 BDYs (or 5 ITRs that overlap 4 BDYs) to hit a victim 20 times at once.


A possible application for this is to fix a grab bug - notice that Julian attempts to grab all 3 Templates.

For some reason, this bug with itr kind 1 grab cannot be solved by simply putting arest.
It would instead be necessary to short out 19 out of 20 of the attacker's ITRs.

That's where Itr Kind 4 (Falling) and Kind 5 (Weapon) comes in.
Both ITRs essentially serve no function if used outside of their very specific purpose of enabling Thrown ITR in falling frames and weaponstrength in wpoint respectively, but continue to count towards the attacker's hit count.

Below is a GIF after the bugfix is applied. Do also notice that Player 2 always gets picked out from the group.


As to whether to use kind 4 or kind 5, that depends on your needs, but there is an important difference.

Kind 4 has friendly-fire(can hit both allies & enemies).
Kind 5 only hits enemies(can still hit frozen allies, but does NOT hit allied state 10).

EDIT:
@Mesujin has pointed out that Itr Kind 12 and 13, which are unused undefined kinds, could potentially be used too in place of Kind 4 (because they have friendly-fire as well). Note that kind 17 and above however would behave like kind 0.

Other applications for itr shorting could involve:
1. Making ITRs only hit allies but not enemies (or only hit if there is an ally and no enemies present)
2. Ensure that an ik8 dialogue box in Stage *always* picks Player 1.
