As your Familiars get stronger, their stats, bonus CP, and skills get stronger as well. In turn, your CP (Combat Power) will also increase. There are three methods of increasing the strength of your Familiars: Level Up, Advance, and Star Up.
Unlike your character who earns EXP when fighting and completing quests, your Familiars can only increase their levels by giving them Familiar EXP Items. These come in three varieties. Outside the events and limited-time tasks, we also listed the sources where you can normally get these items:
| EXP Item | EXP Provided | Source(s) |
|---|---|---|
| Familiar EXP Candy | 10 Familiar EXP | Normal/Advance Summon, Familiar Training (Road to Develop), Story Dungeons, Treasure Maps, Bond Chests from Bond Dispatches. |
| Advanced Familiar EXP Candy | 40 Familiar EXP | Normal/Advance Summon, Familiar Training (Road to Develop), Zodiac, Treasure Maps |
| Mythical Familiar EXP Candy | 200 Familiar EXP | Normal/Advance Summon, Treasure Maps |
As your Familiars level up, the amount of EXP needed to reach the next level will gradually increase as well. As such, higher level familiars will tend to consume more EXP candies in order to level up. However, once you unlock more familiars, it’s reasonable to try to level up all of them rather than focusing on leveling up a single Familiar. This will allow you to maximize the CP boosts that they will individually provide.

Also, you’ll be able to reliably get a good amount of Familiar EXP items from the daily Road to Develop > Familiar Training dungeons so if you’re playing the game regularly, don’t forget to complete this, even if you just Blitz a lesser difficulty dungeon.
