Enhancements

Overview
As a character advances in experience, he will be able to gain and then spend action points on enhancements. A character gains an action point at each rank except those ranks which coincide with a level increase. There are five ranks per level, but only four action points. The one exception is upon reaching level 20, when the character gets the final 4 points all at once, since there are no more ranks to gain. The total enhancement points available at level 20 is 80.

The available enhancement selection is based upon a character's race and class, and consists of improvements to those race and class strengths. For example, a Rogue would be offered enhancements to improve skill at hiding or disarming traps, and a Barbarian would be offered enhancements to improve their ability to Rage.

All enhancements from a class or race stack with other enhancements from a class or race, even when they give identical bonuses. Elven Dexterity and Ranger Dexterity can be taken together.

Ability bonuses from enhancements or equipped items do not count towards enhancement or feat prerequisites.

Enhancements can be reset using platinum or astral shards while in a public area. The platinum cost is determined by the number of action points currently spent, as well as a multiplier determined by the number of enhancement resets you have done recently. When resetting your enhancements, you may choose to reset all enhancements at once or an individual tree.

Pre Mod 3.3
The enhancement system was totally redesigned in Mod 3.3. Before that date, a player could only have four enhancements. However, one line of enhancements only counted as one enhancement. For example, a level 10 dwarf could only select Dwarven Armor Mastery III, he could not select the second nor the first and that counted as one of his four enhancements.

Back in that time, player could not save action points before leveling. In fact, if a player had unspent action points when leveling, he received a warning message.

Once a character had reached the maximum level possible at that time, he received a free action point every 20,000 XP so that he could change his enhancements if he so chose.

Post Unlimited
In Unlimited/Module 9, Capstone enhancements and Prestige enhancements were added. For each class 1 Capstone was implemented and it was announced that for each class 3 tiers of 3 different Presteiges were planned. However, even to this day, many of these Presteiges remain unavailable, limiting some classes' player choice.

On Update 7, class specific enhancements like Cleric Heal I has been replaced with generalized enhancements like Improved Heal I. This also brought down costs of the four tiers of the skill enhancements. Before, tier I, II, II and IV cost 1, 2, 3 and 4 AP respectively. Now, all tiers cost 1 AP each for generalized enhancements. This improved the viability of Prestige enhancements for many builds.

Update 19 Enhancement Pass
Total redesign in the user interface and the way AP is spent.
