How to effectively train at ghost pirates/dt's and so on

Pretty stupid method of training if you ask me. What I'd do is Ice>Flame>Ice the mobs. If you're not afraid of being damaged, leave an octo on a platform, should aggro the monsters so they're mobbed for you - that's good for long platforms (I do that at nest golems). Also, I wouldn't reccomend wide maps - Jumping down>killing>jumping down etc until bottom then use the teleport up and repeat is the method I'd train with, so choose a map that's narrow.
