Seriously, fix the Elemental Destabilization..

[twinkles]

I agree with you that this can be REALLY irritating. But this usually happens on one or more of these conditions:

1. Synth is way above you (6 ranks or more)
2. You don't have the needed synthesis support
3. Half moon - this moon phase seems to complicate synthesis in general

Ofc destabilization can happen anytime during the synth process, there are some ways that help you to deal with them:

1. Brand of XYZ, usually removes destabilization after 1-3 waits
2. Assemble (Woodworking), Piece by Piece (Armorer) seems to have same luck/fail rate despite destabilizing
3. Hand of the Gods prevents a great loss of durability on explosion

Hope this can make your crafting experience more enjoyable! ^^

Also a few more aspects that can improve synthesis stability

1. Stacking more control gear + control food.
2. Make sure you have the correct training manuals. (if one is needed)
3. Many syntheses have sub-jobs that are not listed in the synthesis UI, YG is pretty good about listing these.
4. Abilities that i use for general purpose synthesis. Hands of the Gods, Perfection, Ingenuity, Harmonize.
