Exactly how do attuned enhancements work?

[OEM61]

I have looked for some information, but a search brings back so many hits that the result is a great deal of searching and not finding the answer I am looking for.

Basically...

1 - If I am level 40 and the enhancement is part of a 1-30 set, will it work at 40 or is it capped at 30?  I mean the raw numbers (you know...  +18.5% accuracy or whatever) of the enhancement.

 2 - What about set bonuses for that 1-30 set?  Is there a circumstance where I will lose them?

3 - If I am level 20 but the enhancement is part of a 30-50 set.  Will the raw numbers of the enhancement(s) go down to level 20 quality or will they just not work at all because I went too low?

4 - And now for a level 30-50 set.  Is there a circumstance, say exemping down to level 20, where I will lose the set bonuses?

5 - Am I correct in my understanding that level 50 only enhancements/sets will work no matter what level I exemp down to?

I am just trying to figure out all the conditions where an enhancement / set might fail me. 

Thank you.

From the Wiki:

 

Set Bonuses and Exemplaring:

 

When a character exemplars down to a lower level access to set bonuses (and Global IOs that function as set bonuses) is based on the level of the Enhancement and not the power they are slotted in. Exemplaring more than three levels below the level of the Enhancements renders the set bonuses non-functional. However as long as the character does not exemplar more than three levels below the level of the Enhancement the set bonuses are retained even if the power they are slotted in is unavailable.

Purple (Very Rare) sets, PvP sets, Archetype Origin sets, and Winter Origin sets are exempt from this rule and their set bonuses function regardless of the character's exemplar level. Attuned Enhancements change their level based on the character's current Combat Level so the set bonuses will only shut off if the character exemplars more than three levels below the minimum level allowed for the Enhancement.

Marine X has already posted the info, but to break it down:

 

- The raw stats will always work, no ifs or buts.

- The raw stats are tied to your current level. At level 50 a one stat IO will be 42%, but at level 25 it will be around 32%. Exemplaring counts for this.

- The raw stats stop at the level the IO set stops. If it only goes to 30 then it will always be around 33%-ish and never grow to 42%.

- The bonuses are cut off downwards but not upwards. There is a three level grace allowance though. A level 20-40 will not work at level 16 but will at 17.  It will work anywhere from 40 to level 50.

- As a rule it is best to always slot attuned so that the bonuses can travel with us if we exemplar (within its range) while slotting unattuned (or boosted) IOs will only work within its 3 level range. For example slotting a level 50 crafted or boosted set will have its bonuses turn off at level 46.

- Boosting IOs we don't care about is a good way to fix the missing raw stats a power is missing. For example if you slot four Kinetic Combat for its sweet 3.75% Smash and Lethal defenses the set gives very weak raw stats with accuracy down in the 20%s. But that can be propped up by slotting a Mako quadruple (acc/dmg/rech/end) and further boosting it to +5. Only do this with a max level IO so it has all the raw stats of being max level then further boosted +5 times.

- Purple sets (Ragnorok, etc), PvP sets (Shield Wall, etc), ATO sets (each AT (or class) has two ATO sets that only work for them) and 'event' sets (Avalanche and etc) are immune to the downwards cut off. This even allows to boost them to +5 (with the exception of ATO and event IOs who exist only attuned). Even though this does not bring huge dividends due to Enhancement Diversification that severely clamps down on stats as they approach 100% it can serve to slightly up missing stats. For example five slotting a purple set will end with 89% recharge and 33% endurance reduction. Boosting the acc/recharge and dmg/end IOs of the purple set allows to slightly up those numbers. The benefits are tiny though, but in the late game 5 million is nothing so why not?

If it has a max level then that level +3 is the highest it will increase in power. Most people tend only to use the procs in those unless it's an interesting set bonus

oops... but are you sure about that? because a Miracle heal/absorb caps at 40, with a heal of +38.6%. an attuned one on a level 50 character has a stat of +42.4%, which is exactly the same stat as a lvl 50 generic IO heal.

That's a display issue that goes back to when catalysts were added.  IO tooltips were never updated to display their real value when attuned.  The power's actual stats, and the game engine itself, use the capped IO value.

Out of pedantry, there are still some interesting bugs for some sets.  Some of them enable you to slot an attuned IO at a level where you would not be allowed to slot the lowest available leveled version.  The most useful example of this is Performance Shifter, which has a minimum level of 21, but you can slot it at level 17.  Technically that should be 18.

I want to say that I think I've seen a reverse of this with certain PVP pieces, where I could slot the level 10 version at level 7 (similarly for a few other sets that don't start at level 10), but I had to wait until level 10 to slot an attuned version. Furthermore, I seem to recall that this isn't true of ALL PVP sets. I do know that I've had to wait until level 10 to slot ATOs. I rarely use Winter pieces at low level so I'm guessing they are like ATOs.

 

My memory is a little fuzzy, because I don't always bother with slotting enhancements at those levels.

Most of this is covered.  Attuned is great.  Always attuned EXCEPT Purples.  They are considered attuned anyways.

i just posted a long bug report for 17 attuned sets that slotted early. most only 1 level early, but several 10 levels early.

tl:dr: When leveling up, there is no reason not to buy/use attuned exclusively. Once at 50, never attune purples, PvPs, or anything you want to boost.

 

I think all the questions have been covered, but to try to summarize:

1 - Assuming it's attuned, it will provide the same benefit from level 30 to 50. If not attuned, it will provide the enhancement for it's specific level. It will WORK at 40, but will provide less enhancement than a level 40 enhancement would.
2 - I don't know of any sets with a level under 10, but assuming you mean 10-30, they will stop working if you exemplar to level 6 or lower. In general, set bonuses are lost when below 3 levels of the enhancement (or the set minimum if attuned). In this case, 10 is the set minimum, so 6 is when they are lost.

3 - If you are natively level 20, you can't slot a 30-50 set piece. If you are 27+, but are exemplared to 20, the enhancement works according to the exemplaring math linked by Uun. It can get a little complicated under level 32, so suffice to say the raw numbers will work fine, though not identically.

4 - Yes, you would lose all set bonuses of all 25+ sets if you exemplar to 20.

5 - Yes, purple/very rare/level 50 only enhancements are the exception to the set bonus rule. They are always on so shouldn't ever be attuned in case a boost is necessary*.

 

NB: Level 50 PvP IOs (they are rare/orange, but show 2 different bonuses for PvP/PvE) work the same as purples and should also not be attuned. However, they are different in that they have a level range of 10-50 (purples can only be slotted at 50) so could be attuned and slotted at level 7 so their enhancement bonuses increase as you level.

* This is the reason why you wouldn't want something attuned. Attuned and boosted are mutually exclusive. You can boost an enhancement up to 5 levels to 50+5 to increase the enhancement values of the enhancement above normal values. If you're certain you're never going to boost, then always attuned is just fine.
