Confused on Octopus Attacks and Self casts.

[Groovy]

/cast [target=focus, nodead, harm] Smite

This will try to cast smite ON your focus, what your looking for is the following:

/cast [target=focustarget, nodead, harm] Smite

now keep in mind that the focus target does lag a bit on the alt characters, if your like me and change targets often, it'll take about 2 seconds before the focus target is registered on your alts.

If you want to make sure your main target is always the right target for your alts i would suggest this instead:

/assist main
/cast [nodead, harm] Smite
