Other Undefined Strings:

#23 fixes all the spell string mistakes but not the death due to mana overflux shortly after being punched by another entity string

I noticed the first four in #24 and did fix them in #23.

Regarding death.attack.mana_overflux.player, I've just pushed a commit to #23 that should "fix" this issue -- I simply copied the same string for it. We'll look into giving it a unique string later, but at the very least there'll be one, if we forget.

Nice, but so you know .entity death messages are not a thing, .player appears even if it a mob that attacked the player beforehand
Heres also a suggestion: what about "%2$s ruined %1$s's magic show"

Nice, but so you know .entity death messages are not a thing [...]

Mojang, why?

Thanks for the tip and the suggestion!
