The gnome counts the coins as well, before placing them into a wooden box behind his stall and replies; "I cannot give exact pricing as it depends on artisan how much they charge for the given item and not all artisans capable make them permanent lasting enchant. But if you do go dungeons regularly it will renew the toy's energy by spending there a while, around hour or two should be enough for toy recharge while in dungeon. But usually none dungeon goods last forever, otherwise we would not have artisans specializing in making dungeon goods last longer time or make them permanent."
