Action Point

Each character level in D&D online is divided into 5 ranks (from rank 0 to rank 4). When reaching ranks 1, 2, 3 and 4, you receive an action point which may be spent at a class trainer to gain or exchange enhancements. You may only have 4 enhancements at any time however, and it is common to leave action points unspent when you have found a set of enhancements that appeal to you.

Upgrades of the same enhancement must replace previous versions (e.g. Cleric's Wisdom II will automatically replace Cleric's Wisdom I if you had it). However, you do not need the previous version of an enhancement to take it to its highest version available to your character.

When leveling, any unspent action points are lost (you will receive a warning prior to leveling asking if you want to spend unused action points before leveling).
