Many people in UO are superstitious when it comes to gaining skills. How much is true and how much is fiction? If you think it helps, I'm not gonna stop you. Some things really are just superstition.
This is absolutely false. If you knock a creature's health down to low levels, it does not make it any easier or tougher to tame in terms of skill. The only thing that reducing its health will do is make it move slower, or in the case of fire breathers, make its fire breath do less damage.
Eating only does 2 things in UO: restores stamina and improves health and stamina regeneration. Those are the only things it does. This is a fact, as explained by the Dev Team at an UOHoC. Many people believe that being on a full stomach will improve skill gains or skill success rates. This is completely false.
Many people swear by this to gain skills. Some claim to be stuck in skill gains forever and suddenly start moving again after they die. This is completely false.
Some believe that some servers give more skill than others. By switching servers, you can move from less populated to more populated servers and vice versa. However, skill gain was disconnected from shardwide usage back in early 2000. This meant that the more a skill was being used, the harder it was to raise. This is no longer the case.
Apparently, some people believe that by blessing themselves, it will give them an additional stat bonus. Some use this "myth" to try and transfer a high end pet to someone with inappropriate skill levels. Guess what? It doesn't work that way. You don't get additional stat bonus for adjusting your stat levels artificially (potions, spells).
This is untrue. All creatures spawn with random attributes and skill levels. Their attributes are not tied to their color or body type. This is true with all pets, not just dragons.
Totally untrue. This may appear true, since you may still be raising your taming and lore skills, which will make the pet listen better.
Complete myth. A skill can decay at any time, even if the player is not skill capped. A skill marked up will only raise if there are skill points available, not because another skill marked down "chose" do decay. Skills decay in title order (ie. alchemy will decay before blacksmithing, animal lore will decay before animal taming, etc.), simply because that is their order, not because they "decay" faster.
