Add skill unrestricting or skill cap raising as a prayer boon or sacrifice gift.

In order to preserve role differentiation via different skill distributions, gifted artifacts shouldn’t unrestrict their weapon’s skill; the only way to unrestrict a skill should be crowning. To compensate, your god will somewhat favor giving you artifacts you aren’t restricted in.

You should be able to wield a spellbook when you get crowned to either unrestrict its spell skill if you were restricted in it (the same as it works for weapons), or raise your role’s skill cap in its spell skill by one level, to a maximum of Expert.

When you get crowned, the crowning artifact already exists, and you are not indicating you would like a weapon skill unrestricted by wielding an appropriate weapon, your skill cap in the crowning weapon’s skill should be increased by one, up to Expert. For instance, if you are Lawful but your role normally can only advance long sword to Basic, you will then be able to advance it to Skilled.

Because giving Cavemen a way to get good weapons makes the role less differentiated, and because the roleplay experience of a Caveman is perceived to be best when using a club, they should be restricted in nearly all weapons except for the “caveman basics” such as club, spear, sling, and boomerang.

It might be necessary to make them exempt from getting their skill unrestricted by their god, because if they could still do that, most players would probably just use the same old artifacts at Basic skill, again hurting the role’s differentiation.

Forcing them into using primitive weapons might make them interesting by virtue of incentivizing using attack wands much more to deal with threats; an interesting gameplay change would be for cavemen to get more uses out of attack wands than other roles, but that would make little flavor sense.

Of course, this would require their quest artifact to be changed to either a non-weapon or to one of the types of weapons they are allowed to use.

Archeologists should be able to do experimental archaeology with any artifact weapon to unrestrict its skill. Effectively, this would allow them to train the skill up from restricted to unskilled, which takes as long as going from unskilled to basic does.

If you get crowned while wielding a saddle or while mounted, your god should unrestrict riding skill.

Artifact book (novel?) that when read teaches you one level of any skill. This may include skills you are restricted in (though it might only raise it to Unskilled) and skills past your role’s cap.

Wielding a weapon while getting crowned either unrestricts it if you were Restricted in it, or otherwise raises your skill cap an additional level, up to Expert. Though this is obviously bad for inter-role balance.

If you defeat a monster that generates with an artifact weapon, that weapon’s skill is unrestricted for you, so that you can actually use it. Possibly only do this for monsters that are guaranteed certain artifacts, like Kas in EvilHack, rather than extending it to any random monster.

Remove the feature where being gifted an artifact in a restricted skill unrestricts it to Basic; compensate for this by fixing the balance of artifact base types and the gifting logic so that your god’s first gift to you is never an artifact whose skill you’re restricted in.

Add some mechanic that allows you to pay for training to unrestrict a skill and bring it to Basic. Players of any role are also able to get riding training.

When a Priest is gifted an artifact weapon, they are unrestricted in its skill and their skill cap in it is set to Skilled, rather than Basic.

Multi-skill gifted weapons should unrestrict all of their skills.

Gods may grant a saddle as a sacrifice gift and unrestrict riding skill.
