Standard Hit Points - your HP is reduced when damaged by enemies, and your character dies when it reaches zero.
SP/SP Recovery
One of the most important stats in Circle of Doom.
SP is consumed when using Abilities, or even just swinging a normal weapon.
Better equipment require and consume more SP.
Example) If a character with 100 SP swings a weapon that consumes 10 SP per swing, a total of 10 (100/10 = 10) swings are possible.
However, some equipment and accessories boost your SP recovery when you don them. The SP recovery is shown as '/sec'.
Example) a weapon with SP recovery of 30/sec: just equipping the weapon will replenish 30 SP per each second.
If you equip a weapon that is too burdensome for his/her SP meter, you will be severely limited in the number of attacks possible.
In such case, increase the SP recovery with auxiliary weapons and accessories so that your SP replenishes while it is being consumed to wield the weapon freely.
Luck
This stat affects every chance-related factors that happen in the game, such as:
Chance of an item drop
Chance of a better item drop
Chance of a status effect to be unleashed
Chance of a synthesis (when it is not 100%)
Level Up
You can freely allocate HP, SP and Luck when you level up.
Enhancements
Special functions that can be attached to equipment by synthesis. There are 60+ Enhancements in total.
Each equipment has limits on the number and type of Enhancements it can have.
Up to four Enhancements can be attached to each weapon, and a total of 24 Enhancements can be attached in all (including Enhancements on armor and accessories)
The maximum level of Enhancements is 25. If you synthesize Enhancements of the same type together, the resulting Enhancement level will be a total of the previous ones.
Example of Enhancement Use 1)
Attach Flight to Regnier's Throwing Axe: The Throwing Axe now stays in the air for a longer period, depending on the level of Flight.
Attach Rampage to Regnier's Throwing Axe: The Throwing Axe doesn't just fly in a straight path - it now swings around Regnier.
Synthesize the two Throwing Axes in the above examples together, and you will swing and hover around Regnier for a long time because it has both Flight and Rampage.
If you were to add Absorption to the Axe above, then it will let you leech HP from nearby foes hit by your Axe!
Example of Enhancement Use 2)
Attach Rupture to Celine's Bow: The arrow will split in two when it hits an enemy. If the level of Rupture is high, the split arrows have a chance to split yet again when they strike an enemy as well.
Attach Guidance to Celine's Bow: The arrow seeks and follows the nearest enemy. High level Guidance will sense enemies that are farther away.
Synthesize these two Bows together, and your arrows will split into multiple arrows that seek and strike enemies, which might split again to seek out more enemies!
Abilities
You can learn Abilities in the dream world.
If you wish to learn an Ability, you will receive a quest.
Complete the quest and return to the dream world to receive the Ability you chose.
Depending on how much SP is used, same Abilities will have drastically different results.
Example 1) When casting Magic Shot, tap the button to fire one missile. Press and hold the button to consume more SP, and you will fire multiple missiles.
Example 2) Press and hold the button to consume more SP, and your Vampire Bat Ability will summon more bats who will also be able to Confuse and Fatigue enemies.
Regnier can synthesize Abilities with his Greatsword if it has the Enhancement called "Enchantment".
Synthesis
Synthesis can be done at Idol Sanctuaries.
The resulting item of a synthesis will always be shown on the right side before the synthesis is finalized.
Basic Rules of Synthesis
The resulting equipment's stats will be based on the primary equipment's stats.
The level of same Enhancements that can be attached to an equipment will be added together.
Example) Greatsword with Enchantment 1 + Greatsword with Enchantment 2 = Greatsword with Enchantment 3
The number of Enhancement slots of a synthesized equipment will be identical to that of the primary equipment with higher number of slots.
Example) Shuriken with 2 Enhancement slots + Shuriken with 3 Enhancement slots = Shuriken with 3 Enhancement slots.
In order to have multiple types of Enhancements on an equipment, there must be sufficient number of slots on that equipment.
Example) Shuriken with Multi-Fire 1 + Shuriken with Excavation 1: one of the Shurikens must have two or more slots for the resulting Shuriken to have both Multi-Fire and Excavation.
After synthesis, the Enhancements are sorted by level.
Synthesis of Equipment and Potion
Synthesizing an equipment with a potion will have varying results depending on the potion type.
Example) Equipment + Small Red Potion: deletes the bottom-most Enhancement.
Example) Equipment + Yellow Potion: Adds the player's name tag on the equipment.
Solo/Co-op Game
Character played in a solo game can be used in a co-op game without any limitations, and vice versa.
In co-op game, the HP and EXP of enemies increase in proportion to the number of characters in the session.
The chance for item drops also increase with more characters.
Acts/Sanctuaries/Dream Worlds
There are a total of six Acts in Circle of doom.
Each Act has three to seven stages - most of them have four stages.
On each stage there is a Sanctuary, where characters can meet one of three Idols depending on the moon phase.
You can trade items with the Idols, or ask them to synthesize items.
You can also sleep near the Sanctuaries, and progress through the storyline or receive quests for Abilities in the dream world.
Difficulty Modes
There are three difficulty modes in total.
The Normal mode can be cleared without much emphasis on Enhancements or synthesis - finding/purchasing decent equipment should be enough.
In the Hard mode, enemies will begin to use Enhancements and Abilities, so you will need to strategically plan synthesis, equipments, Abilities and more. Tackling the Hard mode with friends is recommended.
