Guild Wars 2

http://wiki.guildwars2.com/wiki/Mystic_forge_stones

Three items must be equipment of equal rarity, i.e. any combination of armor, trinkets, or weapon.
The chance to upgrade is the same as with normal like-item rarity conversion: 20%.
The stone takes the place of a fourth item of equal rarity, with a type and level equivalent to the average level of the first three items. For example:
Three Level 75 exotic axes + 1 stone = same as four Level 75 exotic weapons; result will be a Level 80 exotic weapon.
Two Level 75 rare axes + one Level 75 greatsword + 1 stone = same as four Level 75 weapons; result will be a Level 80 weapon of either rare (80%) or exotic (20%) quality.
Two Level 62 weapons + one Level 80 trinket + 1 stone = same as four Level 68 pieces of gear, i.e. the result could be a piece of armor, a trinket, or a weapon.

Last days i use these stones with exotic weapons and my results like these:

80lvl exotic + 80lvl exotic + 80lvl exotic + stone = 78 lvl exotic (3 times XXX of accuracy)
78lvl exotic + 78lvl exotic + 78lvl exotic + stone = 75 lvl exotic (hammer of Stamina)

12 exotic weapons + 4 stones were ruined for nothing. Just last try. But i lost more items just did not count. WTF? Something bugged or arena changed something without notification or i missed something?

The range of levels that can be output was increased (in order to cause different skins to have a better chance of being created).

This means that you can get items that are lower then the average of the items you put in.

Don’t worry though, as you aren’t actually being hurt. You can throw those lower level items back into the forge and can get an 80 back so in the long run you aren’t losing anything.

Plus some of those lower level items are worth a lot more than a similar level 80 items due to the rarity of the skin.

All i got are regular skins but 78lvl. I hoped for precursors. If you are right my chances with this change were reduced. Did arena.net explain it somewhere?

Your chances for a precursor are the same as they’ve always been.

You can put 4 level 75 items and get a precursor you know.

As long as the AVERAGE of the 4 items is at least 75, you have a shot at a precursor. You could put two 73s, one 74, and one 80 in the Forge and have the same chance at a precursor that I do when I put four 80s in because the average of the four items in both cases is 75 or higher.

ArenaNet has not explained the details of the system, but they did address the precursor chance. You’d have to dig through John Smith’s posts to find the exact quote.

Thank you. I will try to find.

The MF stone has nothing to do with the results seen (it has the same chance to happen with 4 LVL 80 Exotics). This change was made back in April 2014.

I believe the AVERAGE needed to get a chance at a precursor is 68, not 75 (at least that’s what I have seen in the forum threads where players have done experiments generating dozens of precursors (well over 10,000 forges).

Essentially, the forge change replaced some of the Pearl and other common level 80 exotics you used to get with level 75-79 exotics. The odds of getting a precursor have not changed, and the odds of getting a uniquely named exotic (Dhuumseal, Khrysoar, etc) have seemingly gone up slightly.

This is not exactly right. While one’s chances are the same given they throw in the same level items as prior to the patch since the return has changed so have your chances if you reforge your outputs.

To elaborate: Throwing in 4 level 80 items will have a higher chance than four that are not all level 80. A dev informed us of this a long time ago. Now we have sub 80 output chances which we did not have prior, so IF you reforge your outputs from prior forges your chances overall have decreased. This is due to having less lvl 80 items to reforge after forging initial stock.

So to reiterate: An individual forge chance has stayed the same. Chances overall when including reforging has decreased.

They also promised we would like the MF changes once they were finished. Finished being the key word as most that I’ve seen do not like the changes so far.

Granted I have gotten two pres from the forge, but if I used the gold I threw in I could have easily bought four. I just don’t find buying rewards…well….rewarding, Which is one of my main gripes with this game.

This is not true if the average level of the items thrown into the forge is at least 75. Four rares or exotics with an average level of 75 have identical odds to four level 80 rares or exotics.

This is true for rares or exotics with an average level less than 75. If you throw four exotics with an average level of 72 into the forge, it is still possible to obtain a precursor, but the odds are lower than they would be with four 75s.

As the output of the mystic forge with four exotics of level 75 or higher will always be an exotic of level 75 or higher, the odds of getting a precursor have not changed.

That’s not what the dev told us a long time ago. They specifically said all 80s had a higher chance. I wish the search function worked better so I could quote it. Someone else has to remember the post.

Here is the only thing I can find:

It does say that level and rarity improve your odds, but she does specifically state that all 80s has a higher chance than any other combination.

You are losing, actually. 4 level 80 items (or 3 level 80 items and a stone) can get you a level 75-80 gear. If the average of the components goes down, so does the average of the results (with four 75 gears you can get as low as level 70). Previously, you were guaranteed to always get at least the average level, now you can get less.

So you mix the level 70 with some other 80s and you’re still getting 75-80 items.

Also, I think the “lower level” items drop in tiers, as I haven’t seen a sub 75 item when using all 75s (haven’t done a lot of those though, so I could be wrong).

That is not how it works. At all.
