as many of you may know, toxic revenger is a imba dagger from the first boss in Gnomeregan, the drop rate for this dagger is piss poor and some people dont have a high level mate to help them do boss and reset, so i have compiled a fast and easy strategy for level 29 rogues to do, i did it at 29 for my twink rogue, you should be able to do it a bit lower if u want to.
you will need some healing pots
1. first off go to Gnomerregan ofc
2. stealth until you get to the place where you usually jump down if you dont want to go to the clean zone.
3. jump down on to the large Cog-like thing and stealth as soon as you land
4. regen
5. the guy you are looking for is called 'viscous fallout' so if you want you can make a macro...... /target viscous fallout
6. its not essential but you may want to kill one of the mobs on the outside rim to give you piece of mind incase u aggro one when you fight the boss.
7. wait for the boss near the cog where u landed, he patrolls round, so be patient
8. once he has come to you, cheap shot...backstab/sinister , depends what spec you are, and use your evasion, just fight him as a normal mob but with loads of HP.
9. pot if you need to
10. if the dagger didnt drop run up through the clean zone, go out of the instance, try not to go near the 'irradiated pillagers because they have a dmg aura that breaks stealth. reset instance and try again
it took me about 9 times until it dropped, the drop rate is piss poor but it is a very good twink dagger or good dagger for leveling.
good luck trying to get it
