If you swing a Simply Swords weapon and cannot trigger the holy magic attack, check a few common equipment and mod interactions to get Divine Smite working.
Check Weapon Type and Hand Slot
1. Verify the weapon class: Only greatswords, greathammers, and the special Watcher weapon receive the ability. Confirm your greatsword or greathammer is made from iron, gold, diamond, netherite, or runic materials.
2. Equip in the main hand: Make sure the heavy weapon is actively held in your main hand slot rather than stored in your inventory or placed in the off-hand slot.
Check Required Mods and Keybinds
1. Confirm companion mods are present: This data pack adds spells from the Spell Engine combat system onto heavy weapons from Simply Swords. Both Simply Swords and Spell Engine must be running in your setup for the ability to appear and cast.
2. Resolve keybind conflicts: In big RPG modpacks like Prominence II, multiple mods often share keys. Open Options > Controls > Key Binds and ensure your spell casting button is not bound to the exact same key as another active ability or shield action.
