I got this idea from @cronos4321 but nevertheless, its a great idea and I think this should be considered into the game.
Upon mobs death, spawn electric orb that deal +125% (rank 5) that kill it.
Orbs stay for 3sec and it can make chain if there is more than 1 orb exist like the arc effect or lay trap effect or something.
Say the orb kill astounding number of mobs and spawn another orb deal +125% damage that kills it and spawn another if it kill another mobs and spawn another if it kill mobs and spawn another if it kill mobs. Means +125% damage each time and that is a damage multiplication set just like plagued and frozen.
Those orbs are different from the actual orb skill and should not be affected by hero points because it would be too strong and it wouldn't make sense.
This set goes with the theme of ball lightning which is a lightning that looks like a ball and lasts a little longer than a lightning bolt. 3 seconds makes sense with that theme.
Not sure what to call the set affix but it would be a major buff to shock and hopefully encourage people to build shock builds. Shock is almost underpowered and underrated as well.
That set affix goes well with the shock 12.5% debuff stack up to 4 times as well as paralyse and high voltage set affix.
The set will drop at desert just like how inferno drops at lava, plagued drops at forest and permafrost drops at ice. Frozen drops at a higher floor idk where? The set affix will help newer players too when they find items like that in their journey in dq.
The set affix could be called ball lightning or something like that? Maybe zeus' rage? Not sure what name I could name it for the game. The set affix won't be as good for pvp though since there are no multiple mobs for it to work and just like frozen set, it requires the enemy to die for the effect to take place.
There are many good possibilities I could imagine with this set affix and with enough dmg, it is just as deadly as frozen and plagued (as well as counting the shock debuff effect stacks).
I hope that was a really good idea. I personally think it is because it requires you to be able to kill mobs for the effect to work and it multiplies.
I wouldn't say its op considering the fact that we have plagued and frozen. It would be a big buff for shock though and hopefully encourage players to build more campaign shock builds with high dmg.
For arcane, not sure what could be in place but it would be nice to have an arcane effect (like fire has dot over 2 seconds) of some kind as well as a set dedicated to it that boost its dmg so much.
I do have one question though, why does vanish get affected by stealth hero point 40. I think it shouldn't because vanish is a completely different mechanic since it is mythic and different name. Vanish is vanish , stealth is stealth. No other mythic from my knowledge can be affected by hero point.
It is unfair for other class because rogue can get 5 second vanish and stealth while other class have to get 1-2 second duration.
Btw that shock orb will have a different animation to cosmic orb and orb skill because it cannot be affected by hero point since it has a different mechanic to the orb skill.
If anyone has better ideas for a shock set, feel free to list them down thanks .
This orb btw only appears if the enemy died by a shock effect or shock attack to make sense for the effect otherwise it would be an any element orb or an easy two element build. This means it will not work if you don't use the shock element. Same as how plagued only works if you used the poison element and frozen works if the enemy is frozen by ice and died while staying frozen though the enemy can die from other element while frozen and the frozen explosion still works.
