Mouseover macro not working with Havoc

[Barsukis-chamber-of-aspects]

Hello everyone,
I’m trying to make a mousover Macro for the spell Havoc.

I have wrote:
#showtooltip Havoc
/cast [@mousover] [] Havoc

However it does not cast Havoc on my mouseover target. I tested the same configuration where I replaced Havoc with Chaos Bolt and it was working fine. I am very curious why it is not working. Is related to Havoc in some way?

Thanks.

your mouseover is missing a letter, but you can shorten it in a different way

#showtooltip
/use [@mouseover][] havoc

The missing letter was a mistake while I copied… But your Macro actually works – Thank you!
However, I don’t understand why. The only difference it has from mine (disregard the missing letter, it was with it in my macro screen) is that Havoc is not capitalised. Are macros case sensitive? Why did it work with Chaos Bolt and not Havoc?

[Lentat-anetheron (Lentat)]

No, they arent case sensitive, but I must admit I missed something you propably should add

#showtooltip
/use [@mouseover, exists][] havoc

Otherwise it wouldnt target your target if you dont have any mouseover target.

Fair enough. Initially, I simply copied this macro from Icy Veins. It was not working, and then I started fiddling around to see why it didn’t work.

#showtooltip Havoc
/cast [@mouseover,harm] Havoc; [harm] Havoc

Guess I will never know what the problem was, but thank you nonetheless!
