Something I was wondering about:

If I make a pet with special attack1: medium poison and special attack 2: strong poison, will they stack against mobs? Is it possible to make a pet with 2 strong poison attacks and if so will they stack? Also, what exactly does disease do as a special against mobs? Anything beside just cause wounds? (That doesn't seem very useful, although they would be fun for PvP.)
