Familiars provide unique modifiers, minions or additional spells when you have all 12 spells from a spellbook. To activate or powerup a familiar, you need to sacrifice 20HP per cast. In Elementals Mode, the familiar is enabled on game start and powered up to level 3 (although it can not be powered up more). The following tables outline what each familiar does when powered:
Arcane
The Arcane Familiar is the Unstable Portal. It was added with the patch on December 21, 2020, as a much requested change because the Book of Arcane was the only book without a familiar.
Familiar specific changes:
- Every other level (levels 1, 3 & 5) increases minion summon limit by 1 per level to a maximum of 7 slots.
- Level 1: Learn the spell Little Devil. Little Devil's cooldown is decreased by 1 for each Arcane familiar level you have.
- Level 2: Learn the spell Arcane Mist.
- Level 3: Arcane Tower starts with 50 hp.
- Level 5: Arcane Energizer is permanent (once used). Arcane Tower starts with 75 hp.
| Icon | Spell | Tier | Type | HP | Number of Charges | Initial Charge Time/Recharge | Maximum Damage | Spell Description |
|---|---|---|---|---|---|---|---|---|
 |
Little Devil | 1 | Arcane Minion | 10 | Infinite | 7-3 | N/A | If three weren't enough, here's another one. Does not end your turn. |
 |
Arcane Mist | 2 | Targeted | N/A | Infinite | 0/5 | 15 Arcane per turn over 5 turns | Like Aura of Decay, only Arcane. |
Flame
The Flame familiar is the Harpy. Each level increases the damage of your flame spells by 10% over the base damage (up to 50% more damage). The familiar also increases the radius of your flame spells and adds more projectile to Rain of Fire, Rain of Arrows and Napalm.
Familiar specific changes:
- Level 5: Learn the spells Meteor Shower and Fire Wave.
Icon Spell Tier Type Number of Charges Initial Charge Time/Recharge Maximum Damage Spell Description 
Meteor Shower 5 Personal 1 5/- 15 - 90 Targets all enemies from above and showers them with napalm for maximum mayhem. Fire Wave 5 Personal Infinite 0/1 25 Blast your enemy out of the arena by creating an intense ball of fire that knocks everyone but yourself far and wide. Works best by making contact.
Stone
The familiar for the complete Stone book is a Pet Rock. It reduces damage taken (by you and your minions), usually by 5 (at level 5) for each hit to you or your minions. This means that although a single shot spell such as Fire ball would be reduced from 50 to 45, multiple shot spells such as Thunder Shock would be reduced from 5 to 1 each, making total damage only 10. The familiar never gives immunity to damage, no matter how small. The familiar will also reduce the amount of HP you recover from Heal Sphere. In Elementals Mode, the damage reduction is a maximum of 3 (even at level 5).
Familiar specific changes:
- Level 1: Learn the spell Stepping Stone with Cooldown 5(reduced by 1 per level).
- Level 3: Learn the spell Summon Mountain Goat.
Icon Spell Tier Type Health Number of Charges Initial Charge Time/Recharge Maximum Damage Spell Description Stepping Stone 1 Targeted N/A Infinite 0/5-1 N/A Places a small stone. Does not end your turn. Summon Mountain Goat 3 Minion 50HP Infinite 3/5 N/A Great for reaching high places and being annoying.
Storm
The familiar for the Book of Storm is the Storm Cloud. This will hover over the user and "amplifies" the damage of Thunder Shock, which fires an extra shot per level. It also decreases the recharge time for Storm by one turn per level, and increases the amount of lightning strikes when casting Conductor Rod.
Familiar specific changes:
- Level 5: Wind Shield has a 7 turn cooldown. Gain the spells Whistling Winds and Electrostatic Charge.
| Icon | Spell | Tier | Type | Number of Charges | Initial Charge Time/Recharge | Maximum Damage | Spell Description |
|---|---|---|---|---|---|---|---|
 |
Whistling Winds | 5 | Personal | Infinite | 0/5 | N/A | Gain flight for half a turn. Your Arcanist falls down when your turn ends. |
 |
Electrostatic Charge | 5 | Ball | Infinite | 0/1 | 25 | Stays on the battlefield for 10 turns. Recharges every time anyone casts Thunder Shock/Chain Lightning and/or when a Storm goes off. |
Frost
The Frost familiar is the Frost Sprite. It increases the jumping ability of your minions, and makes the water you stand on freeze, turning your life into ice platforms in increments of 5-1 hit points depending on the level of your familiar.
Familiar specific changes:
- Level 1: Gain the spell Frost Leap.
Icon Spell Tier Type Number of Charges Initial Charge Time/Recharge Maximum Damage Spell Description Frost Leap 1 Ball Infinite 0/1 N/A Leap across the map. Max power is increased for each Frost familiar level you have. Aim it like every other ball spell. This spell does not end your turn.
Underdark
The Underdark familiar is the Soul Jar. As with other familiars, you use it by paying 20 health points per level, which you can do up to 5 times. If you die then you will respawn at the Jar's location with 20 health points for each level of familiar.
The Soul Jar is the only familiar that doesn't follow you, instead remaining where you were when you last increased its level. The only way to move it is to use it again in a different location, as long as all 5 uses have not been used.
If the Jar falls into the water but is still floating, it will function (but you will be summoned in water and have to use your turn to teleport out). However, if the Jar is sunk it will then work as if you died while in water. (A Jar can be sunk if a player or minion gets drowned at the Jar's location).
The Soul Jar will not work if:
- the user is killed by Light damage (or the Sphere of Healing, if they were a Lich)
- the user dies while in water (the finishing blow must knock the opponent into the water), or if the Jar was sunk
Familiar specific changes:
- Level 5: Rain of Chaos is less random.
Overlight
The familiar for the Book of Overlight is the Cherub. Each time it is charged, it allows the player to gain 1HP worth of shield (similar to the Protection Shield spell) per turn, up to 5HP of shield per turn when charged to Level 5, to a maximum of 50HP worth of shields by the cherub. You can still go over 50HP using the Protection Shield.
Familiar specific changes:
- Level 5: Shining Bolt does 55 damage. Sunder can do 100 damage. Rising Star has a 5 turn cooldown.
Nature
The Book of Nature's familiar is the Fungus. It increases the size of Thorn and Vine Bombs and also increases the amount of arrows fired by Elves.
Familiar specific changes:
- Level 5: Learn the spell Forestation. Vine Bridge/Vine Bomb/Thorn Bomb have one extra use each.
| Icon | Spell | Tier | Type | Number of Charges | Initial Charge Time/Recharge | Maximum Damage | Spell Description |
