Runes of Magic US / AU

I have seen some macros that only cast skills if the player bares or the target bares a certain buff/debuff. Eg, using snipe onlyif AD is on the target.

I've done some tinkering and I can't quite figure it out.
I need help making a macro that casts lowblow only if shadowstab is on the target. And one that casts wound attack only if both bleeds are on the target.

Any help would be much appreciated.

I hear that spamming an attack macro inputs the skills faster than diyce. This is also for r/wd btw, and I hear diyce doesn't weave charge chop was effectively as a macro spam would.

The macro would be SOMETHING like this:

/cast Charged Chip
/cast throw (nonglobal cooldown)
/cast Together
/cast wound attack (with the conditional macro code)
/cast low blow (with conditional macro code)
/cast shadow stab

Clicking the macro would set off one skill at a time, putting the top one as a priority. And it would skip WA and LB untill the required buffs are on the target.
I have done this rotation manually, but it's clunky and with lag it is slow.

I have been told CC weaving is faster in a macro, which is basically the whole key to this classes damage output

Thank you rovie, I'll try it out as soon as I get in game!

update: i tried the code you posted rovie, and it didn't work. i just copied and pasted it and tried it while applying shadowstab to the target, and without. not sure if im just stupid, or i just fail at code lmao

Edit: i was helped in game, i just had to add an "i" after the "target" in the begining of the macro and add a ";" at the very end
