From A to Z about: Fused Hero & HES Bonus Formula

Greeting our Heroes,

Today, we'd like to bring you all information regarding HES Bonus Formula and Fused Mechanism.

HES Bonus Formula

HES Bonus (or quota), in short, is one hero's limit of earned HES. The HES bonus will be cumulative as you earn HES from all sources (except Tower Conquest mode). HES rewards of each hero will drop to 2 percent when the HES bonus is maxed out.

Initially, all heroes start at 0 cumulative on total HES Bonus (for example, 0/10000). The amount of HES bonus to be filled for each Hero is 50% of 200% HES earned (Campaign mode, Hard mode, Daily Raid, Daily Quest). Before the HES bonus is full, players still receive 200% of the HES earned.

For example:

Before, winning a battle earns 20 HES.
Now, winning a battle earns 40 HES (200%). Before reaching the HES bonus, the player still gets 40 HES. At the same time, each hero will accumulate 10 HES towards the HES bonus limit.
If one Hero is maxed out of quota, the amount of HES rewards received by that Hero will decrease to 2% of the total 200%.
If all 4 Heroes are maxed out of quota, in this case, the HES reward for that battle will be 1.6 HES.

Here is how to calculate the Total HES bonus for one hero.

Let:

A: Start HES Bonus

n = Hero level

B: Cumulative cost HES up to Level (n+1)

X: Total HES Bonus

In which:

When the Hero is at level 1, the HES Bonus rate is determined by the rarity of Hero (60%), Pet (30%), and Hometown (10%).

A = 60% * Start Hero + 30% * Start Pet + 10% * Start Hometown

Rarity (Hero/Pet/Hometown)	Start HES Bonus
Common	2000
Uncommon	2500
Rare	3500
Epic	6500
Legend	15000
Mythic	30000

B = Cumulative cost HES up to Level (n+1)

	Level	HES	Level	HES	Level	HES
	1	0	21	68	41	218
	2	4	22	73	42	222
	3	6	23	78	43	226
	4	10	24	84	44	230
	5	14	25	88	45	234
	6	20	26	92	46	238
	7	27	27	96	47	242
	8	35	28	101	48	246
	9	43	29	106	49	250
	10	51	30	111	50	254
	11	51	31	117	51	286
	12	52	32	123	52	318
	13	52	33	133	53	350
	14	53	34	143	54	382
	15	53	35	153	55	414
	16	54	36	165	56	446
	17	54	37	177	57	478
	18	57	38	189	58	510
	19	60	39	201	59	542
	20	64	40	213	60	574
Total cost HES (cumulative)		760		3271		9931

The total HES Bonus is equal to:

X = (1 + 2%*n) * A + B

For example: Hero Death Level 10 (Uncommon) - Pet RedPanda (Rare) - Hometown Snow Mountain (Common)

A = 60% * 2500 +30% * 3500 + 10% * 2000 = 2750

B = 261

X = (1 + 2%*10) * 2750 + 261 = 3561

Fused Hero

The purpose of launching this fused feature is to help prevent hero inflation.

To increase the quota or HES Bonus received for each hero, you need to use the fused feature. When you fuse hero A into hero B, all remaining quota of hero A will be transferred to hero B. Fused heroes are low-level, weak heroes that you don't want to use anymore. You can:

(1) choose them from available heroes
(2) buy them from the market

And of course, the hero that received the above fuses is the most used, strongest, and most earned hero on the team.
