When I first got into "Sky Era", like you, I thought this game was just about changing clothes and flying to see the scenery. Until I did an in-depth study of the demon spirit development system - good guy, the numerical design is quite good. Today I will move out the data from my two days of actual testing to help you save at least 30% of the resources and detours.
Let's start with the core conclusion: Demon spirits of the same quality will have a difference of no more than 5% in basic attributes, but their skill coefficients and growth curves will be very different. The optimal strategy is not to blindly pursue five stars, but to "lock the core skills, raise one, and concentrate resources to feed it to the breakthrough threshold."
Let's first look at the attribute composition of the demon spirit: the four basic items of life, attack, defense, and speed have a fixed growth rate for each level (the growth rate is fixed, and the star rating only affects the initial value). For example: a three-star demon spirit with an initial attack of 86 will have an attack of about 860 when it reaches level 30; while a four-star demon with an initial attack of 120 will have an attack of about 1,200 by level 30. But the key is - the skill enhancement brought about by breakthroughs is the qualitative change.
I actually measured 20 demon spirits of different star levels and found a rule: when the demon spirits break through +3 and +6, their skill damage coefficients will increase by 20% and 35%. This means that even if you take a three-star demon spirit, as long as it breaks through to +6, the skill damage may exceed that of a four-star monster that has not broken through.
Who should the resources be allocated to first? Here is a simple numerical comparison table (I am too lazy to post a picture, so I will dictate it): At the same level, a three-star demon spirit with a breakthrough of +3 has an output per second (DPS) of about 4200; while a whiteboard four-star only has 3600. Therefore, if you only have a small amount of Breakthrough Stones on hand, it will be more cost-effective to give them to a low-star demon spirit that has been trained first, rather than spreading them to all high-star demon spirits.
Let's talk about the Demonic Stone Tablet—that is, the talent tree. Each demon spirit has 3 branches, the left side is for output, the right side is for survival, and the middle one is for general use. There's a mathematical trap here: many players like to attack all over, but there are diminishing returns in practice. I calculated the improvement brought by each point of talent: the first 3 points of attack talent increase attack power by 5% per point; starting from the 4th point, each point only adds 3%. So the optimal solution is: to output the demon spirit, first hit 3 points of attack, then hit 1 point of critical hit (about 8% critical hit rate), and then go back and hit the remaining attacks. In this way, the total income is about 12% higher than that of the full attack route.
As for the team formation of demon spirits, don't believe in the metaphysics of “water, fire, and earth are in conflict with each other.” According to actual measurements on the same level and at the same level, the damage bonus of water-attributed demon spirits to fire-attributed enemies is only 8%. However, if you place two demon spirits in the front and back rows, the damage will be doubled after triggering the "linked skill". Therefore, the core strategy is to "form a team around skill linkage" rather than attribute restraint.
Finally, let's talk about resource planning. The breakthrough stones, experience pills, and gold coins you can obtain every day are limited. I have calculated that before level 70, the optimal efficiency is to feed the main demon spirit to 5 levels higher than the level (for example, your character is level 60 and the demon spirit is raised to level 65), and then the other demon spirits remain stuck at about 10 levels lower. Because the experience required for each level increases exponentially, while the attribute gain is linear. After a certain level, the price/performance ratio is extremely low.
To summarize the steps:
Choose a demon spirit you like with a high skill coefficient (go to the illustrated book to see the skill multiplier, and those with a multiplier greater than 2.5 will be given priority).
Focus your daily resources on her and prioritize her breakthrough to +3.
Talent click "3 attacks + 1 critical hit" cycle.
When teaming up, look at the "linkage" keyword in the skill description, and try to get two demon spirits that can trigger the linkage.
Don't be in a hurry to reach star level, break through first. Only the basics are added to increase the star, and skills are added to the breakthrough.
One last reminder: the "cute" attribute in the game does not represent strength. Those chubby-looking demon spirits are likely to have the lowest output, but the control skills are disgusting - such as slowing down by 50% for 3 seconds, which is a magical skill in PVP. So don't just look at the panel, look at the skill descriptions.
Okay, I've given you the data, the rest is up to you to try. Feel free to criticize me if you have different opinions, but I only accept actual measured data. 🛠️
