<p>I asked this question through a a support ticket as there doesn't seem to be anything recent about this being discussed on the website-</p><p>"<strong>Holding down a key with a heavy object does not violate any Tibia rule.</strong> If there's anything else I can help you with, please let me know." -Kind regards, Leomax</p><p>So yes, this means for achievements like walking on fire, underwater, snow, you can have an object help you, and not using your fingers is perfectly fine.</p>
