Most efficient form to summon Trolls in big numbers?

I didn't mean to say that drakes are a joke. It's just that you will often be ridiculed for them "oh, he spent gems on drakes". Dragon master does make them easier to mass. And, en masse, they are not bad.

Vitriols are personal favorite of mine. It's really hard to mass them though.

And yet, somehow baalz managed to get hundreds of those in Lapis... that was a very scary game.
