yikes, with stats like those, 3-4 star Level 50 recipes should be a yawnfest even from NQ mats

(I'm not a huge crafting aficionado so my rotation could be much better but it does get the job done)

Makers Mark
comfort zone
Flawless synth (as many as it gives)
inner quiet
Steady Hand 2
Hasty touch until 20 durability
Masters mend 2
Steady hand 2
Hasty until you hit 8-9 IQ stacks
Steady hand, great strides, Byregots
should only take 2-3 careful synth 2's to finish the craft.

Use precise touch on a good if it's not at the end of a cycle and you have Steady hand up, otherwise hit tricks on it.
