Vampirism Iron's Spells Compatibility
Java mod listed for Minecraft 1.20–1.21. File opened and checked on 5 Oct 2026; downloads from the MC Java Mods app on Android.
Vampirism mod now integrated with Iron's Spells Blood magic. Use your blood to reduce cooldowns, use blood ray and bite to restore blood! Also aware of…
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Vampire Spells Addon connects Iron's Spells 'n Spellbooks with Vampirism and changes selected spell behavior for vampire players.
Current behavior
- Ray of Siphoning and Devour restore configurable Vampirism blood to a vampire caster from delivered health damage. The amount is observed after absorption and other damage processing, excludes overkill by capping it to the target's health before the hit, and never requests more blood than the caster can hold.
- By default, a vampire pays mana for every mana-consuming Blood School spell. When the full mana price cannot be covered, every such spell except Ray of Siphoning falls back to an atomic blood payment and spends no mana. If the blood price cannot be paid in full, the spell effect is stopped without a partial debit.
alwaysUseBloodForVampireBloodSpells = truechanges those non-Ray casts to blood-only mode even while mana is available. Creative casts, non-mana cast sources, and recasts keep their normal free-resource behavior. Ray of Siphoning always keeps its normal mana cost and continues to restore blood.- Devour's configurable mana multiplier still applies only to vampire casters; its scaled final price is also the basis for a blood payment. Every Blood School spell cast by a vampire uses
vampireBloodSpellCooldownMultiplier, which defaults to2/3for a cooldown that is 1.5 times shorter. - A vampire's Ray of Siphoning animates toward the caster rather than toward the target. Its guide text also explains the spell's night-creature origin in all languages supported by Iron's Spells.
- Holy spell damage dealt to a Vampirism NPC vampire is doubled regardless of who cast it. Delivered holy health damage reflects onto a vampire player caster.
- Holy healing damages vampire casters/targets and suppresses the corresponding heal. Holy utility spells damage a vampire caster, clear any targeting data created during pre-cast checks, and cancel the cast.
- Cast and heal correlation state is bounded and cleared on lifecycle boundaries so nested or interrupted actions cannot affect an unrelated later action.
- Server-side tuning is stored per world in
<world>/serverconfig/vampire_spells_addon-server.toml.
