I wanted to create this posting as a advisory to all those that are planning to level up during Early Access before and After the official release of Stormblood. As in the title in this post, those that pre-ordered Stormblood will gain access to this incredible item....a earring described by SE to provide the traits and bonuses listed below while it is equipped:
VIT+5
STR+5
DEX+5
MND+5
INT+5
Increases EXP earned by 30% when level 50 and below.
Now the crucial part of this posting is asking you to look at the part where it says "Increases EXP earned by 30% when level 50 and below." You read that right.....that means that all the XP you earn as a Level 50 or below will grant you a bonus on top of the already available bonuses in game for having a job at 60. So why may you ask is that awesome? This one item will make farming Level 50 Dungeons the most ideal way to level from 50-60 and quite possibly even higher levels than that. That is also not including the bonus to xp from doing your daily roulette or since you will be fighting mobs at equal level while synced.....you will also receive Chain XP!
Chain XP in FF14 is described here: http://finalfantasy.wikia.com/wiki/Chain_(term)
As per the information in the webpage above, "Experience Chains work similarly to Final Fantasy XI exp chains. They can only be gained while fighting monsters that are of the same level or above the player's current class level. Chain bonuses stack with linking, guildleve, level difference and party bonuses."
So if you look at the way EXP Chains works in FF11:
Chain# Bonus
1 20%
2 25%
3 30%
4 40%
5+ 50%
Time (in seconds) 1-10 11-20 21-30 31-40 41-50 51-60 61-75
Chain #1 50 100 150 200 250 300 360
Chain #2 40 80 120 160 200 240 300
Chain #3 30 60 90 120 150 180 240
Chain #4 20 40 60 80 100 120 165
Chain #5 10 20 30 40 50 90 105
Chain #6+ ?? ?? ?? ?? 50 60 60
With this data, you clearly see that if you add up all the bonuses to XP....from the 50% you get for having a Lvl. 60 already, then adding in the Ala Mhigan Earrings 30% buff, with food XP bonuses, farming Level 50 Dungeons with a Pre-made Group if you are a DPS/Healer or solo queing as a Tank is the best and optimal way to level during this time to get to 60. I would also add that HW dungeons can be farmed this way as well as long as the mobs you are fighting are the exact same level as you to get the chain xp shown above but at a lose of the bonus 30% xp from the earrings. Then during those times you are no longer the same level, you can return to level 50 dungeons to receive the bonus chain XP once again!
Lastly, this method is guaranteed to be better for leveling than POTD or any other method as long as you are in a Premade group as a DPS/Healer or Tank solo. If you are a healer/DPS and you truly cannot find others to party with.....at that moment POTD is a better option for you since you can more than likely have a shorter que time than waiting for a level 50 dungeon que! But remember, rested XP cannot be used for POTD and if you are farming floors 51-60 you are level 60 inside and the bonus xp you get from the Ala Mhigan Earrings does not apply. POTD only gives a static amount of XP per 10 floors completed as seen here:
So good luck to everyone in Stormblood and I hope this information will be useful for all!
