Magic items that increase class levels

[PathfinderEspañol]

There are a few magic items that increase your class levels (for some features only).
That's ok, but what happens if you are a high level character (say 19 or 20) and the item gives you the ability of a 21+ level class?
*Does the item become useless for you(after all, it is usually too cheap for a high level character)?
*Do you figure out epic levels?

Some items:
Candle of Invocation (+2 cleric levels for Spells per Day and max spell level)
Robe, Monk's (+5 monk levels for AC and unnarmed damage)
There are more in the APG.

Nothing basically. All class abilities cap out at 20, you receive no extra benefit from them.

For example I remember being part of a discussion on how the Monk's Robe caps your unarmed damage and AC at level 15.

Most of the class features that have such items made to improve them are based on some sort of formula that you can easily extend to higher levels, if you want to do that. I would, in my games.

SOME class features cap at 20, not all.

Monk Unarmed damage and all casters spells per day cap at 20.

Monk AC and Movement speed do not.

Sneak attack progression does not cap at 20.

Spell effects do not, so if you are a 20th level cleric using an orange ioun stone (+1 caster level) and a bead of karma from a strand of prayer beads (+4 caster level). You cast mass heal as a 25th level caster and restore 250 HP (the 25th level amount) to all your allies in range.

In the unlikely event it were ever to come up. If say, I had a lv 20 Monk and drew the Deck of Many Things card that bumped me up a level, I would likely just take a level of fighter, or some other class.
