What is Halidom in Royal Blood?
Royal Blood Guide
1. Your Halidom Rank - shows your current Halidom EXP and rank.
2. Bonus Stats - bonuses you get (all characters in the same account), based on your current Halidom rank.
3. Enhance - sends you to the menu where you actually enhance your Halidom rank using Prisms.
It is not unusual for MMO games to have some secondary or tertiary means to get your in-game characters stronger and more efficient on various tasks. Some games might call them, Ki, or Chi but in Royal Blood, you basically have the same system set, and is called Halidom. You will gain access to the Halidom after completing the introductory chapter, "Hallowed Sanctuary - True Successor".
As defined on the accompanying story, the "Halidom" is an ancient relic used by Harslans to build their kingdom and to drive Legion away. Given that you are a heir to the throne, you have access to its power. The more you claim of it, the more powerful you become.
What this means gameplay-wise, is that as your Halidom rank rises, your PvE stats and bonus daily recharge reward amounts increases just as much - making it more efficient and more rewarding to do activities at a time. To increase you Halidom rank however, you'll need to use the game premium resource called "Prisms".
Additonal Tips:
-The Halidom Rank you have is shared between all characters (on your account). Which means if you have a chance to upgrade it a lot on your first character, you'll make the most out of it when you try to create a second, or third, or fourth character in the game.
Prism is the most valuable resource in the game which is primarily used to enhance your Halidom. Additionally, you can donate Prism to your guild and in the Auction House. You do have the opportunity to get Prisms for free via log-in rewards (depending on your calendar schedule), Battlefield, and as rewards to some of the Daily Activities. Otherwise, you'll have to shell out cash through IAPs to get them.
