very strange maybe someone knows about this.

the topic is

the 2 ios regular ios that are recharge only.

2(lvl 40+5) base recharge of firey embrace is 3. mins. 2(lvl 40+5) are 113.5% value to bring recharge time down to 1 min 24 secsonds.

i just realized i did that i had lvl 40's that i (+5)'d

so i said o well and i bought a 50 and was about to throw it in there then (50+5) that one. what the combat attributes pop up screen tells me is the value of 113.5% stays the same and the

replace says (1 min 24 secs -0.9%)

so here is my question how could it go down 0.9% if its 5 lvls higher? that to the best of my understanding is not how addition works. 45 is less than 50

is there a reason for this or a previous thread.

The reason it does this is that boosting an enhancement to +5 *isn't* equivalent to boosting it by 5 levels. If it were, boosting a level 40 recharge by +5 would only increase it from 38.6% to 40.5%, which hardly seems worth the expenditure. Instead, each enhancement booster increases the power of the enhancement by a flat 5% of its base value - so +5ing an enhancement increases its bonus to 1.25 times its original strength. So, a 40+5 recharge gives a bonus of 38.6% * 1.25 = 48.25%, significantly *more* than a plain level 50 recharge's bonus of 42.4%.

Thus, as you saw, replacing a level 40+5 recharge with a level 50+0 one isn't actually an improvement. However, replacing a 40+5 with a 50+5 *will* be - a 50+5 has a bonus of 53%. That said, it's not going to make a difference of more than a fraction of a second in recharge, especially since it looks like you've also got a +recharge alpha (two 40+5 recharges don't give 113.5% enhancement by themselves, but that's about right for those plus a spiritual core 45% rech boost edit: whoops, no, it's not - I'll rerun these numbers later). As far as I can tell, going from two 40+5 to two 50+5 ought to take the recharge from 84.1 to 83.6 seconds - is 0.5s really worth the expenditure, especially since the difference will only get even smaller once you factor in your global recharge?

That is great info! I've never bothered with the boosters because using them is such a slow process but a 25% gain in enhancement value spread across all the enhancements that will take it (even discounting for ED) that's a notable boost.

i'm in the slow process of subbing my lvl50 reg and some set I/O's for lvl35+5 versions on my Crab Spider Nephila. Basically all non Purple, PvP and Proc's will be changed to the lvl35+5 version.
I noticed that the % is a little higher using lvl35+5 vs lvl50. Also, since they are level 35, they still work when i exemplar to level 32 if i need to.
