Enjoy it for a while longer though ;)
Using Puncture with World Splitter equipped seems to semi-permanently increase the aoe of some skills with "area" tag. The bug persists between monolith echoes but not floors of a dungeon. There is no time limit, and maybe no size limit, though the increase in size slows down the bigger the aoe gets.
Puncture does not appear to benefit from the size increase, and instead it acts like the size increase gets stolen by other skills.
Unequipping World Splitter does not remove the size bonus, so you can use other weapons with the turbo AOE. This does stop the size from continuing to grow, and just keeps it at wherever you stopped,
Shrines also benefit from the bug, and maelstrom for example gets gloriously huge, bigger than the screen.
Sorry if this has been reported already, and doubly sorry if it hasn't and I just exposed your beautiful build/exploit! u/ekimarcher let me know if you need any more info.

Well, I'm glad you already apologized to everyone else because this was not on the radar and I have figured it out. It's caused by the way Penumbral Ambush and World Breaker interact. Today was the last day.
edit: the rabbit hole goes deeper, this was actually really good to catch, thank you.
Sad/glad I could contribute to the destruction of a glorious bug
It was a really sneaky one. Just had to move one line of code.
Was it caused by the addition of mana cost on that node or the shadows, or something else entirely?
A combination of those and something else entirely.
Once you're done squashing the big can you share how much deeper it went? Maybe a showcase of silliness that was possible but we all missed? That's be great fun.
I kinda don't want to show the ways it can be abused until the fix actually rolls out and that won't be until April. But if you remind me, sure thing.
