This strat is banned form the speedrun leaderboard, so the actual WR is still 2:23 (also completely insane). The fact that this is completely working as intended just shows that this game absolutely nails destroying reality with complex magic.
Calling this glitchless is a little misleading, unless you’re suggesting that carrying spells over from one run to the next was intended / normal functionality. This also requires a mod-constructed wand that isn’t possible to get in a non-modded game.
It’s still awesome from a theorycrafting standpoint, but there’s no one arguing that this is a legitimate speedrun.
