The only thing you need to know is to adjust the
Data - Base Order ID to any string that has the same Target-type with your ability.
Let's say your Channel is a Target-unit ability, well, you should change the Order ID to Target-unit based string order, such as thunderbolt (Storm Bolt Base Order ID) / chainlightning (Chain Lightning Base Order ID) / etc.
Here's a a few list of String Order ID;
Target-unit
acidbomb
chainlightning
charm
cripple
curse
Target-point
blink
blizzard
carrionswarm
earthquake
Instant-target
avatar
berserk
phaseshift
waterelemental
Make sure after you set the Base Order ID, you
must follow the order string for it to work.
Let's say you set the Target-unit spell ID to thunderbolt, you must use this action to make it work;
-
Unit - Order (Triggering unit) to Human Mountain King - Storm Bolt (Target unit of ability being cast)
If let's say you set it to chainlightning, this will work;
-
Unit - Order (Triggering unit) to Orc Far Seer - Chain Lightning (Target unit of ability being cast)
You just have to find the right action depending on your pre-set Base Order ID.
NOTE: AND MAKE SURE EACH SPELL HAS ITS OWN UNIQUE ORDER ID FOR A SINGLE UNIT, ELSE YOU WILL BE OVERLAPPING ITS ORDER ID.
