Iron's Spellbooks Effects
Iron's Spellbooks Effects are the status effects added by Iron's Spells 'n Spellbooks. They are applied by spells, magic items, summoned creatures and some enemies such as the Ice Spider. The mod registers 37 effects. Beneficial effects make the affected entity stronger, faster or harder to hit. Harmful effects weaken it or punish it. Neutral effects belong to neither group.
Most effects change combat or movement numbers through attribute modifiers, so their strength scales with level (amplifier). The per-level values are listed under each effect. Effects that cancel or redirect damage run on the server. Effects that only change visuals, such as fog and invisibility rendering, depend on the mod's client code.

Evasion
Evasion is a beneficial effect that makes the affected entity teleport away from an incoming attack, so the attack deals no damage. The teleport moves the entity a short distance to a free, grounded spot. The game makes up to 24 random attempts within a radius of about 6 blocks, which grows on each failed try. The number of attacks that Evasion can avoid is set by its level, and the effect is removed when those hits are used up. Evasion does not stop fall damage, damage that bypasses invulnerability, or damage types that are tagged to bypass it.
Abyssal Shroud
Abyssal Shroud is a beneficial effect that dodges attacks in the same way as Evasion, with the same exceptions for fall damage and damage that bypasses invulnerability. Instead of a long teleport, it moves the entity a small step to the side onto solid ground, then turns the entity to face its attacker. It plays a teleport sound and spawns smoke particles.
Heartstop
Heartstop makes the affected player invulnerable for its duration. Damage taken during that time is not lost. It is added to an accumulated total, which is dealt back to the player when Heartstop wears off. The accumulated damage is 50% of the damage taken. The player's heartbeat sound speeds up as the accumulated damage grows relative to current health. It beats once every 2 seconds when the total is 0 and twice per second when the total equals current health.
Angel Wings
Angel Wings is a beneficial effect that grants spectral elytra-style wings, so the player can glide while the effect lasts.
Ascension
Ascension is a beneficial effect that gives lingering weightlessness. It reduces gravity by 85% of its base value, so the affected entity rises and falls slowly. It is the effect applied by the Ascension spell.
Charged
Charged is a beneficial effect that adds 5% per level to movement speed, attack damage and spell power.
True Invisibility
True Invisibility is a beneficial effect that makes the affected entity invisible, including its armour and held items. It is applied through the entity's invisibility state, so it works on mobs as well as players. A holder of the Invisibility Ring can see invisible entities, so the effect does not fully hide the affected entity from that player. See Rings, Amulets and Charms.
Fortified
Fortified is a beneficial effect that grants absorption, a buffer of extra health that is used before normal health. The absorption amount grows with its level.
Vigor
Vigor is a beneficial effect that adds 2 maximum health points (one heart) per level.
Hastened and Slowed
Hastened is a beneficial effect that adds 2.5% per level to movement speed, attack speed and cast time reduction, and 5% per level to mining speed. Slowed is the harmful counterpart. It applies the same reductions with negative values, so it lowers movement speed, attack speed and mining speed by the same amounts and lengthens cast times.
Chilled
Chilled is a harmful effect that reduces movement speed by 20% and doubles the incoming freeze time of the affected entity. A creature that becomes fully frozen while Chilled is kept in an ice tomb for 5 seconds.
Immolation
Immolation is a harmful effect. Each application adds a stack, and each stack lasts 15 seconds. When the creature reaches 3 stacks, it explodes. The explosion has a radius of 6 blocks and deals damage that falls off with distance. It only hits entities with a clear line of sight, and creatures in the blast are Immolated in turn, so the effect can spread through a group.
Rend
Rend is a harmful effect that reduces armour by 5% per level, so the affected entity takes more damage from each hit.
Blighted
Blighted is a harmful effect that reduces outgoing damage by 5% per level and incoming healing by 10% per level.
Soul Burn
Soul Burn is a harmful effect that reduces incoming healing by 5% per level.
Airborne
Airborne is a harmful effect that makes the affected entity vulnerable to kinetic damage. When it moves horizontally into a wall fast enough, it takes flyIntoWall damage of 4 plus 0.5 per level.
Guided
Guided is a harmful effect that attracts nearby projectiles toward the affected entity. It also forces the entity to glow, so it can be seen through walls. It is applied by the Guiding Bolt spell.
Aspect of the Spider
Aspect of the Spider is a beneficial effect that increases the damage the affected entity deals to targets that have a poison effect, by 5% per level.
Oakskin
Oakskin is a beneficial effect that reduces incoming damage. The base reduction is 10%, with an additional 5% per level, and the total is capped at 75%. It also reduces movement speed by 25%, so it trades mobility for durability.
Instant Mana
Instant Mana is a one-off beneficial effect that restores 25 mana per level plus 5% of maximum mana per level when it is applied.
Gluttony
Gluttony is a beneficial effect that converts food the player eats into mana, based on the food's nutrition value.
Echoing Strikes
Echoing Strikes is a beneficial effect that makes non-magical attacks create an echo. The echo is either a spectral sword that slams down in an area, or a piercing magical arrow that shoots the same target. Echoes deal a percentage of the original attack's damage, 5% per level.
Thunderstorm
Thunderstorm is a beneficial effect that makes small bolts of lightning strike nearby creatures every 2 seconds. Creatures within 20 blocks horizontally are eligible.
Volt Strike and Burning Dash
Volt Strike and Burning Dash are beneficial dash effects. While active, the affected entity moves rapidly in a straight line and takes no fall damage. Each entity it strikes during the dash receives 20 ticks of invulnerability. Volt Strike also explodes on impact with a blocking surface, dealing damage that falls off with distance inside a radius of 4 blocks and throwing the entity back.
Planar Sight
Planar Sight is a beneficial effect that lets the player see creatures through solid material. On the client it also changes the fog to show the surroundings more clearly.
Antigravity
Antigravity is a neutral effect that produces weightlessness. It reverses gravity slightly, so the affected entity drifts upward.
Frostbite
Frostbite is a beneficial effect from the Ice Spells school. While it is active, any fully frozen creature the player kills turns into an Ice Shadow. The Ice Shadow shatters into icicles after 5 seconds or when it takes any damage. The shatter damage is 1 plus the level of the effect, multiplied by spell power.
Fall Damage Immunity
Fall Damage Immunity is a beneficial effect that prevents the affected entity from taking fall damage while it lasts.
Ice Spider Lure
Ice Spider Lure is a harmful effect that attracts Ice Spiders. When it is applied to a player, it calls 8 ice spiders to hunt that player.
Internal and summon effects
Several registered effects are used by the mod's summoning system rather than by the player directly. The summon timers (Vex Timer, Polar Bear Timer, Summon Swords Timer, Raise Dead Timer and Summon Horse Timer) track how long a summoned creature stays in the world. Sacrificial Mark is a neutral marker used by spells. See Summoned Creatures for the creatures that these timers track.
Tips
- Evasion and Abyssal Shroud can avoid a fatal hit, but they do not stop fall damage or damage that bypasses invulnerability. Carry some other form of protection as well.
- Heartstop protects against burst damage, but the accumulated damage is dealt back when the effect ends. Heal to a safe level before it runs out.
- Blighted reduces the healing a creature can receive, so it is worth applying before a fight with a healing enemy.
- Immolation can spread through a group of creatures. Keep harmful targets spread apart when they carry several stacks.
