As far as +ing gears go, I personally am all about 'Click'-'Click'-Re-'Click' etc, until Alche-Isaac comes out with 'Don't blame me if it breaks!'.. THEN I go for it! lol
(even if I have several 'attempts' enr wise, etc..)
Point being obviously, for me, and since/when 'to me' that I 'paid attention', I personally have had that much better luck on +ing gears, when that 'p.o.s Isaac' says 'Don't blame me..' lol I've also kept/keep in mind too though, making sure ALL gears on hand/equiped/in pran inv/etc are all freshly 'repaired'..
I'm sure it's all pure 'chuck' luck no matter what/how/whatever/etc we do, but me personally has had 'THAT' much better luck, making sure that s.o.b says 'Don't blame me..' lol :-!
