I would have to actually have the item in my inventory for both of those approaches to work. Lootdb.com only have a few of them.
Create a new macro. Add command input line. Enter "/use_itemvdl 1358062844" and do that for every item. Click Ok.
BUT ... the bug with this is that, if ya open the macro again, you will just see blank "<drag item here to use>" box instead of the command line "/use_itemvdl 1358062844" if the item is not present in the character's inventory. This is not a problem as long as ya do not click ok after ya open the macro; if ya do click ok, then the /use_itemvdl commands are erased from the macro and ya gotta redo the entire macro.
So, this is a one time macro setup when done correctly ... For my "use power item macro", I have :
Dark Heart (Adept) use_itemvdl 1358062844
Dark Heart (Expert) use_itemvdl -1090779696
Dark Heart (Master) use_itemvdl 1497639127
Shard of Essence (Adept) use_itemvdl 2110730487
Shard of Essence (Expert) use_itemvdl -1816047141
Shard of Essence (Master) use_itemvdl 1954118876
Followed by other items such as signets, power roots, potions, manastones that I just dragged and dropped into the macro since I can obtain the items from crafting or vendors. The proper /use_itemvdl commands of these items can be used as well.
This allows me to use one button to cast any power item, AND I do not have to remember to check my inventory to know if i actually have a dark heart or shard of essences. I have a seperate hotbar that keeps me up to date of recast timers. Each time I click the macro, the macro will only cast the items listed that are in my inventory, one item at a time per macro click, from top to bottom. Also, added the heroic starter cast at the end of the macro to ensure the last power item is not also cast.
I am doing the same for heal items BUT ... Unlike the shards and hearts, there are many many more versions of the Defiler's Crystallized charm group heal item. I do not need to be aware of the item's recasts so I will not have the Crystallized charms on my hotbar.
Unfortunately, lootdb only have a couple of the tier8 ones and a couple lower tier. I am just wondering if anyone could share the item link. Just copy the item link in-game, then paste it in a reply to this thread. The item link will look something like :
\aITEM -1700639885 788372606:[Crystallized Essence (Journeyman)]\/a
Not expecting one person to give all this info, just post what you have available at the moment.
Thanks to anyone with Defiler characters willing to give input. I appreciate the time and thanks for reading.
