All about: Leveling Monsters
There are two parts to leveling your Monsters.
The first one is to fight with your monsters. Taking land, attacking land, attacking other things on the map and taking Monster Lairs in your City will help level your monsters up. Once they have gone up a level, you will have a Stat Point to spend on one of the four base stats, Attack, Defense, Intelligence and Speed.
If at any point, you are unhappy with where you placed your Stat Points, you can reset your Stats with either a token or Gold.
Leveling up Skills
You can also level up your Monsters Skills.
Click on a Monster and you will see it’s details. You can see the Skills box on the right hand side. Depending on the rarity of the card, it may have 2 (Common Monsters) or 3 (Uncommon and higher) skills to level up.
You must level up the monsters 1st skill before you can unlock the others.
There are two ways to level up your monsters skills. Research and Skill Up! (aka Fusion). When using Research to up a skill level, you can research one level at a time which will cost resources and time.
If you have duplicate monsters you can fuse them to level the skill up.
To see if you can level up a monster skill, you simply need to look out for the wolf head with the green arrow on top of it. You can see them on the monster cards and on the skills themselves.
To view more details on a Skill, click the down arrow next to the Skill name, where you can view more information about the skill and the current level. Under the description of the Skill, you can see the Fuse, Acquire and Research buttons.
If you select Research, you will be taken to the Research Skill section, where you will see what you need to research the chosen skill and how long or how much it will cost.
If you select Fuse you will be taken to the Fusion page.
The monster you are leveling up is on the right hand side. The monsters on the left are the ones that can be used to level up the skill.
Please note: Any monster you use for this will be consumed and removed from your inventory, whether the fusion was successful or not. You will gain souls whatever the outcome.
Once you have selected a monster for consumption, you will have a choice of using Gold or Silver ingame currency to complete the fusion and the percentage chance of success. If fusion is not successful on the first attempt, you will be given the chance at another go at the cost of some Gold.
Acquiring skills is similar to Fusing skills. You can acquire skills on empty slots and replace skills on non-native skills.
If you select a skill or an open empty slot, you will be taken to the Skill Details box. If there is no skill there currently, you will be able to Acquire a skill from another monster. If it is a non-native skill, you will be able to replace it if you so choose.
