Once a person is in a separate universe, they must abide by the rules of the dimension. Depending on what world they're in, they may change appearance altogether. However, they may still access abilities and powers that they were capable of in their host dimension because of it "feeding" them their original power. Which allows them to be at their peak no matter where they are.

Would this make alchemic items stop working as there are no laws of alchemy in the other universes?

On the opposite, if that applies, then anti-magic abilities wouldn't work in the Wisdomverse as in that verse, alchemy follows the rules of nature perfectly.
