What is the Blacksmith?
Updated November 16th, 2018
The Blacksmith is a feature which is accessible from the moment you start the game. It allows you to upgrade your hero equipment.
Only weapons, trinkets, chests and boots can be upgraded at the Blacksmith.
The Blacksmith requires 3x copies of an item and and a small fee of 
Gold to create 1x copy of the upgraded item.
Example: 3x
→ 1x
The Gray Dwarves’ Blessing Event allows you to upgrade 1x full set of equipment at once for a much higher fee of

How to upgrade equipment
Upgrading your items to 6⭐ is way more important than you would think. A 9⭐ hero in full 6⭐ equipment can have ~50% more Power than the same hero in full 4⭐ equipment.
Let’s find out whether to upgrade equipment through the Blacksmith or the Gray Dwarves’ Blessing Event.
The mathematical calculations can be found here.
Blacksmith
| From 3⭐ equipment | |
| Upgrade | Cost |
| 3⭐ → 4⭐ | 6.4M |
| 3⭐ → 4⭐ → 5⭐ | 27.2M |
| 3⭐ → 4⭐ → 5⭐ → 6⭐ | 91.6M |
This means that using the Blacksmith to upgrade 3⭐ equipment all the way up to 6⭐ is actually a tiny bit cheaper Gold wise than through the Event. You also save 4000x which makes it very worthwhile.
The only problem is that it costs an large amount of 3⭐ equipment. It requires 27x 3⭐ equipment to create 1x 6⭐.
You can receive 1x 3⭐ equipment from the Light/Dark part of the Heroic Miracle Event as well as summoning the hero of the week during the Heroic Scroll Summon Event. Thus, the ways of acquiring the necessary gear is very limited.
| From 4⭐ equipment | |
| Upgrade | Cost |
| 4⭐ → 5⭐ | 8M |
| 4⭐ → 5⭐ → 6⭐ | 34M |
Using the Blacksmith to create 6⭐ gear starting from 4⭐ gear costs around ⅓ of the price compared to starting from 3⭐. That is an incredible low amount to spend in relation to the huge power increase you receive.
It costs a total of 9x 4⭐ equipment to create 1x 6⭐.
You can receive 4⭐ equipment from the Shelter Event and Treasure Box Event.
Gray Dwarves’ Blessing Event
| From 4⭐ equipment | |
| Upgrade | Cost |
| 4⭐ → 5⭐ | 40M & 1500x |
| 4⭐ → 5⭐ → 6⭐ | 100M & 4000x |
Now you may wonder if it is worth to upgrade your items through the Gray Dwarves’ Blessing Event since it is more expensive than using the Blacksmith.
But since 3⭐ and 4⭐ equipment is relatively difficult to get in large quantities upgrading items through the Blacksmith takes a lot of time. By paying a higher fee of you get to skip gathering multiple full sets of equipment and can upgrade 1 set of 4⭐ equipment directly to 1 set of 6⭐ equipment. It is very worthwhile.
