Ideal spots to farm minions

There is totally no need to waste minions and lose valuable equipment (sometimes unique!). So, how does one farm them?

• Brown minions -- go and kill sheep near Mellow Hills. After you kill them all, quickly march back to the tower gate and return. Take a full-brown setup with you and help them with your highly-enchanted sword. That's very quick.
• Red -- go to the tower dungeon and kill dwarvern flamethrowers. Take red minions for distraction -- they don't take any damage from fire. If you are careful enough, you won't be damaged by the flames. They provide a lot of souls... But be careful when they explode.
• Green -- I didn't really need a lot of them, so I don't really know which way is the most effective, but that's the moment where bugs are really weak and minions are easily disposable (they typically don't use high-level equipment). Greens themselves are very situational because there is a limited number of spots on each enemy to latch on. And if they can't latch, they take damage, so don't take more than like 7 greens with you. If you need them to infuse weapons/armor (why?), bugs again...
• Blues are the same story. You won't need many of them in practice, but blue bugs are weak. You may also go with no minions and simply kill giant frogs yourself.

Bug farming isn't very effective with browns and reds, sheep/flamethrower farming is both quicker and easier.

It case you mess up, you may always put some blues at the entrance -- just don't let the enemy come to them. If you need resurrection, send just one and guard his path.
