Arena 123 Macro with Strangulate and Asphyxiate

Hello, can someone help me writing a Arena 123 that shows Asphyxiate Spell Icon if i dont skill Strangulate? i really dont know how i can write this after a hour of testing and googling

Not sure how you want to hand differentiating between arena 1-3 so here’s a version for just arena1.

#showtooltip
/cast [known:47476,@arena1] Strangulate; [@arena1] Asphyxiate

If you want to set it up so it falls back to your current target if arena1 is dead or doesn’t exist:

#showtooltip
/cast [known:47476,@arena1,harm,nodead] [known:47476] Strangulate; [@arena1,harm,nodead] [] Asphyxiate
