? The only one which you really unlock is Warped terrorbirds (the rest are pretty easy without I'm overlooking some). There not too bad at all if you know what your doing. Just wear melee gear and the moment one starts ranging you flick on protect from range, then 2 seconds later turn it off. As they will either safespot themselves or come into melee range (I cycle 2 birds using this as it allows me to always have 1 lined up for the next kill). 5 monkfish and a bunyip is more then enough for there melee damage (best to bank twice during a task as they're easy to get to and drop a lot of decent things). I did a task of 130/140 in about 1 hour with my questionable stats and made over 300k from the drops (2 rune shields, 2 rune warhammers and a lot of bolts, runes, feathers, tar and tips). My only issue with them is there lack of charms otherwise they would be one of the better tasks. I'd still take warped terrorbirds over black demons any day.
