Upgrading/Fusion

Hello Hero Upgrading and Fusion Guide

In Hello Hero, the only way to make your heroes stronger is by upgrading them and then fuse them into a stronger one.

Upgrading Your Hero

To upgrade your hero, you will need to sacrifice another hero to successfully upgrade it. Heroes that are upgraded will have a +X at the end of their names. You can upgrade it to +5. When you have a level 30 hero upgraded to +5, you can use it for fusion.

You will be spending a lot of your gold upgrading. Gold will be used even if your upgrade is unsuccessful. The rarer the hero, the more gold it will cost.

Fusing Your Hero

Fusing your heroes will give you a hero of a higher rarity. In order for the fusion to happen, you will need:

• Both heroes must be level 30 and fully upgraded at +5
• Both heroes must have the same rarity(two 2★ heroes/two 4★ heroes)

Fusion is always 100% success rate and never fails. You will always get the next level ★ hero. If you fuse two 3★ heroes, you will get a 4★ hero.

Bonus Tips

When upgrading, you will want to take a look at this chart:

Rarity of the Hero Sacrificed	Difference	Success Rate

5★	0★	100%
4★	1★	50%
3★	2★	25%
2★	4★	10%
1★	5★	1%

You can gamble and always use heroes with a lower rarity to try and upgrade your desired hero. However, similar star heroes always gives a 100% success rate.

My tip to you is to use a hero that is 1★ to 2★ below the desired hero for upgrading. This way, the success rate is higher and won’t be way too expensive in terms of gold.
