Skill trainer

A skill trainer is an NPC that can teach a roleplaying character a standard set of skills in the current campaign. In addition, trainers can also teach characters any non-elite skills from the campaign that are unlocked on the account. Trainers can be easily identified by the "[Skills]" suffix in their name.

Purchasing a skill
Each skill costs a skill point and an amount of gold that depends on the number of skills already purchased by that character. The first skill costs only and progresses up to a maximum of  for the twenty-first and all subsequent skills. See Notes for the detailed progression.

Cost savings
There are three ways that PvE characters can save money they might spend at the skill trainer:
 * Skill quests are free; often, they are also quick and easy. Beware of diminishing returns: some of the later skill quests can be long or tedious.
 * Skill tomes allow characters to learn unlocked skills and either free (through drops) or relatively cheap (via trades with other players or through zaishen coins).
 * Hero skill trainers in Nightfall and Eye of the North will teach you skills in exchange for zero gold and one hero skill point.

Other alternatives

 * Signets of Capture can be used to learn skills earlier than you might from a trainer, but the signets costs the same as any other skill.
