I've done this a few times now, but it's possible to get a Tortodrone to kill itself with it's own spike attack.
You guys might want to fix that and up his health by about... Double.
It only takes me 3 charged attacks of my thwack hammer to bring the poor, depressed guy down.
And it takes two of them to get him mad enough to attack.
Actually since he is found at an early stage where newbies like myself would usually hang around, it makes sense for his health to be that low. Lol for me, it takes a long time to kill me... But for experienced players, dead in a snap...
