==Thorns & Conversion==

This is another very cheesy trick, and can often be dangerous by accident. If you are a melee character, never play anywhere near another player who is converting monsters, and has the Thorns Aura, either on a Merc or a Paladin, or even a Druid who might be using the Spirit of Barbs, though the damage on that is so much lower it's not a real risk. The reason is that when Conversion ( the Paladin or Assassin type) wears off, the monster will go back to hostile, and be hittable, but the Thorns aura will still be on them, invisible, for several seconds.

Auras are refreshed every 3 or 4 seconds, when the game checks them, not perpetually, like the aura under the Paladin's feet. If you are doing big melee damage, you can instantly kill yourself on a monster with an aura you can't even see. This has been a problem since D2, and is worse in D2X with thorns on mercs. However since only Paladins and Assassins can convert monsters, and an Assassin has to have a Thorns Merc, it's not too hard to see this one coming, and avoid it.
