If the Enchanter’s Arcanum is installed in your Hold, you can use the Arcanum as you perform enchantments, and gain benefits for doing so.
Any Skill Checks you make for the purpose of enchanting gains a +5 bonus while you are using the Arcanum.
If you cast an Enchantment spell while using the Arcanum, you can choose one of following additional effects or benefits:
The duration of the Enchantment is extended by up to 5 times as long.
If the Enchantment can deal damage, it does 2 additional damage on hit.
The Enchantment does not consume its Available Cast when cast. Does not apply to scrolls.
The item affected by the Enchantment cannot lose durability.
You expend an Available Cast of the Enchantment and the AP of the spell, and the Enchantment is inscribed upon the item in runes, and the item receives none of the effects of the Enchantment. You, or a creature with the enchanted item equipped can spend the amount of AP required to cast the spell to activate the runes upon the item, applying the enchantment. The runes last indefinitely, or until activated or dispelled.
