Help with cross class skills

[Alisi]

Flawless Synthesis + (can't remember the name of the skill which allows like 10 FS without reducing durability) - the problem here is the cost two cross class slots to use this.

Maker's mark. I love this skill. This has been a godsend. It takes up two slots but it doesn't cost any dura. The stacks are determined by the recipe level and you only them if you use MM as the first skill you do.

Manipulation - IMO, no very useful, Master's Mend only cost 4 CP more for basically the same effect.

I didn't like Mani when I was leveling but, now with the new 35 dura things, I've found this to make the whole thing very helpful. Getting HQ seems a whole lot easier when I use this. Strangely, I don't feel that way about this when it's 40 dura. Doesn't seem to work as well for some reason. Probably all in my head. XD
