Amplifying Tome — the Basic Ability Power Item

400gold

Slightly increases Ability Power

Amplifying Tome is the cheapest Ability Power in the shop: 20 AP for 400 gold, which prices it at exactly its own cost. Most AP components start from it — Lost Chapter, Fiendish Codex, Haunting Guise, Blighting Jewel and Aether Wisp among them — so it is often the first thing a mage buys on a short back.
