Code:
/micon "cover"
/ac "cover" <t>
/ac "cover" <tt>
This will enable you to cover the target of your enemy, in case it runs away from you, while still being able to use it on a DPad selected target.
As this is a reactional ability, you still need to be fast and the usefull situations are rare, sadly.
For instance, if one mob is running away from you, it might be wiser to just provoke+range attack it back, instead of covering, letting it run to its new target and losing this ~2 seconds till you provoke it off.
Regarding cover you should note:- Range is limited to 10yalms
- If the covered target will move away more than 10yalms, the effect will end
- Only physical attacks
