Tridents also drop off of the queens guards. We have killed them with 2 toons (50 spearo and 50 Druid regro/nut) and a bunch of pow/heal/end potions. Here a trick we used.
1. Be grouped, hero about 3500/4000 units away from well.
2. Druid targets closest guard turns on attack and runs up and hits it once. Turns around and while SPRINTING to hero turn off attack, and pops a heal potion if needed.
3. Hero kills druid agg of melancholic faeries.
4. The Guards and queen can only go around 1500 units away from well. All the guards attention is currently on druid.
5. Hero pops end and moves to guard farthest from well. Druid has to stay out of range from other guards but close enough to heal hero.
6. Hero should save end towards the end of fight with gaurd cause queen will heal it.
7. Hero loots. And both med.
Notes: Sometimes hero may have to deal with 2 or 3 gaurds, personally never had more undirect attention from druid. It may also take the druid 1 or 2 runs to get guards far enough down hill to make this easier. Be quick as possible without recklessness, the guards will move back up to queen after a couple mins. Side note, there is also a dagger and a mace drop.
