Non-passive to passive spell help?

I'm trying to turn bloodlust into a passive hero ability like critical strike. Does anyone know how to make a non-passive spell passive?

I edited the particulars of bloodlust in the abilitiesdata.slk so that it's range and cost etc were the same as critical strike but when the hero learns the spell it still needs for the spell to be clicked to come into effect - and then it doesn't actually appear to work because none of the animations take effect either.

Any ideas?

Rather than trying to edit the spell data itself, you could make use of a trigger. Have a trigger that periodically creates an invisible shaman next to the hero, cast bloodlust on him, and then go away. The time increment should probably be slightly less than bloodlusts duration so he'll get bloodlust renews before it goes away. Only problems here are these... it can be dispelled, and every so often you will hear the sound effect for bloodlust being played :P Anyway, its a start

Err, I don't quite understand how an attack speed buff would be passive in that sense... I mean, it wouldn't make any sense having X % chance to increase attack speed, because it is based on each hit. Now, if you want something that just increases attack speed overall, your best bet is to use Endurance Aura as a base.

I may be reading Bloodlust wrong - I'm trying to create a new spell called weapon mastery, like the ability in AD&D. So I wanted to increase attack speed, and movement speed - isn't that what bloodlust does?

That's a pretty cool idea actually, a trigger just might do the trick. Still is it actually possible to make a non passive spell into a passive one?

Well, Fork is right, use Endurance Aura instead of Bloodlust as Tauren Chieftan's Endurance Aura increase both movement and attack speed ;)
