New Abilities Tips and Advice?

[warcraftmodding123]

Are there rules and methods in making new abilities to avoid crashes and make working new custom abilities?

 

[TheLordOfChaos201]

there is a thread called, 'what makes the world editor crash' you should look for it

other than that don't make the computer target or use non existing stuff.

for instance, deleting an item and then asking a unit to use last deleted item
