I would like for there to be a quest that will allow players to practice dealing with the various traps in the game. It wouldn't give any XP or rewards (except maybe a token for the first completion to encourage people to be aware of it) but it would provide a scaleable area where players can learn how to deal with traps. It should contain examples of common implementations of traps (blades, anklebiters, spinny death blades, flamethrowers, etc) and allow the user to specify both a difficulty and a base level (so a character could say "show me what traps generally look like for a level 5 Elite quest).
The DCs do not need to be exactly the same as traps in the field, but should be in the same general range. This would let trappers gauge whether they're ready for certain content.
The main goal of this quest would be to provide a setting where all players can practice avoiding traps. Many traps in the game can be avoided partially or completely with careful timing and control. However, currently the only way to practice the skill of trap avoidance is to spend time going into a quest with the trap in question and practicing there. This often means that a character has no practical method of practice, because a single mistake would lead to death.
More experienced players know the little quirks and tricks to avoid traps, and have had years of running and rerunning quests to learn the skills. However, newer players don't have that experience, and are generally expected to already know how to handle traps. A training quest would give newer players an option for testing different techniques and ease the learning curve for the game.
