Sacred Chime Hammer +10?

So I just started a new game for the first time in awhile, and a really chill invader shows up, makes a huge ring of Prism Stones, drops a bunch of items, and dips. We waved and bowed and shiz, was very wholesome

But 2 of the items he dropped were the Sacred Chime Hammer +5, and the Dark Sacred Chime Hammer +10

I don’t really do infusions much, (since so many YouTubers screamed that split damage was ass back in the day lol) so I could be totally misunderstanding. But doesn’t this weapon only go up to +5? Kinda makes me scared it’s hacked or modded or whatever, and I’ll get soft banned or something XD

It only has like 30 more physical damage over the basic +5, and everything else he dropped was super normal. Mostly just like enough soul items to level up like 10 times, and some cool late game armor

(I’m on PS5, btw if that matters. I don’t really know how hard it is to modify the game on console)
