Hey Labreris, You summed it up nicely haha. I tried my best explaining it there, here’s another look how it works:
Just like Kazakus in Hearthstone, baseline Kazakus should mix two Ingredients for one spell effect. In the trivia of him, the developers asked themselves; “what if the players could make their own card?” I tried translating that into Hots as much as I could. Same in Hearthstone how Kazakus Potion text is generated dynamically, same would be for Kazakus Q, depending on Ingredients he adds and talents he takes. (Not just talking about adding talents’ text at the end of each ability text, like what we do have now).
Baseline Kazakus has 2 Ingredients available and after each talent tier that is not heroic or storm talent, he unlocks a new. This is to avoid him being too overpowered from the beginning of the game. The Ingredients limit per potion helps in that matter too. The stats of each Ingredient effect are also intentionally under-tuned because it’s taking into consideration more than one effect in one spell.
And then there are talents: most of them serve as potion recipes that Kazakus could learn alongside each Ingredient. Because every Ingredient is unlocked at every talent tier, this same tier would be centered about that Ingredient. Through talents, Kazakus can enhance his role as Support or Assassin. Talents also make it possible adding more than two Ingredients, enhancing the effects of one Ingredient, but some of them sometimes lose their own effect, some even have side-effects and adding more Ingredients also means it costs more resources, so it should be managed properly.
At first glance, one could say he has 7 secondary abilities, but in fact they are all one ability. One should note that if Kazakus used a Potion he can’t use another one for 5 seconds, they are all bound to his Q cooldown. Even the passive Ingredient that Kazakus has is compensated by giving him so much low base Basic Attack damage. If damage Kazakus decided to heal an ally (which is very small amount of health baseline), he is going to sacrifice dealing damage until the next Q is up. That said, Kazakus players should be flexible for every situation, not just blindingly sticking to their talented Potion Recipes.
Interestingly enough, when I wrote this concept the first time, I gave him 9 active abilities and made it part of the concept theme (Game Changers), as he’d be the first hero that’d receive a unique UI and Hotkeys profile that allows him to use 9 active buttons.
But then I backed down a bit haha . One scrapped Ingredient was Mystic Wool that made it into his Heroic (thus why we have three) and the last one was his level 20 Ingredient “Ichor of Undeath” that I think, it’d have made his enemies a bit salty . I’ll be adding all scrapped ideas soon. One last Ingredient left out is Stonescale Oil, but its effect has been covered by some talents and there’s just not much space anymore.
The additional resource bar I also couldn’t leave out, it’s an essential part of Kazakus lore. His Red Mana Trait gives a nice warlock-feeling to him as well.
Hopefully that also answered your question, as said before all the secondary abilities are bound to his Q.
As a side-note, I have to be honest here, I’ve never played Dota 2 and that’s the first time I actually check Invoker out. There are similarities in which they both make up their own spells. Kazakus Ingredients are directly inspired and taken from his actual card Ingredients from Hearthstone, while his talented Potion Recipes are inspired from both WoW and some of other Hearthstone cards. I’d like to think of Kazakus (hopefully) being unique enough in that regard and that he isn’t just all about mixing spells, he still has so many other tools in his kit that (hopefully) would make him even more unique, such as Enchanted Chains and Portal. Both of which are also inspired from his background story and concept art.
If anyone still has any question, I’d be more than happy to answer them.
