Change death recap: Stop trying to list champions/abilities and just show damage type.
Death recap is a nightmare and extremely buggy. Since it's been almost 9(?) years of this thing not working, don't even try to make it complicated. Just break it down like this:
Physical damage: (Number) (Percentage) Magic damage: (Number) (Percentage) True damage: (Number) (Percentage)
It doesn't really matter who dealt the damage, what matters is how you itemize against what's killing you.
