Yeah man the list is not full, and indeed lol it's poorly translated:/

It's target, aka:

laststatus , lasttarget , lastattack.

laststatus - target on a player status of which you dragged the last. Last attack - target on last attacker.

So, what I meant actually is that you use uo options and use target next there. To cast spell on someone who you choosen by in-client targetnext you should use laststatus

uo.waittargetobject('laststatus')
