I have a question about Rank 10 local quests. My armorer is lvl 13 and i don't have any trouble making items around that level. But somehow when i do the Rank 10 local quests, they fail most of the time. I don't understand this. Is there a secret difficulty or am i the only one who have this problem? I's very frustrating.
Some of the Rank 10 leves require "larger working conditions" meaning they want you to get synthesis support.
In order to do this you must either goto the guild and pay to "use the facilities" or goto the nearest Aerth Crystal and "use the camp facilities."
See if that text pops up in purple in your log before you synth. It will say "this recipe requires larger working conditions" Also when you confirm recipe it will say what level of support you need. The different levels are only offered at the crafting guild. Camp crystal facility support only offers 1 level. I assume its equal to the level 1 support from the guild but cost as much as the level 2 support from the guild.
Hopefully this is your only issue.
Also might be time to invest in crafting gear and/or new crafting tools.
