Skill Chains with/without triggers

[AionCannonzSC2]

Idea from playing AION: the tower of eternity, is this possible to do in the data editor without triggers?

Say you have a hero with 2 spells like fireball and fireblast. You can only cast fireblast right after using fireball. Each ability has its own cooldown. The chain is broken if A: fireblast is still on cooldown, or B: you use another spell instead of fireblast.

Seems like this needs a lot of triggers or even a completely custom UI, but do you think it can be done with only data editor?

Not really too difficult
Create an integer variable.

Event -> Unit casts Fireball
Condition ->
Action -> Set [variable] 1

Event -> Unit casts Fireblast (set 6, begins)
Condition -> (Abs[variable] = 1)
Action -> Cast Fireblast

Event -> Unit casts *any other spell*
Condition ->
Action -> Set [variable] 0

It's a think outside of the box way of doing a boolean.
