I'm totaly lost with spiritbound... what is the best IL to convert? please

[Nutz]

I dont see how 2.3 broke the materia system. Grade IV materia shouldnt be 100%. If anything it was a welcomed change IMO

Why shouldn't tier IV materia be 100% on much more expensive equipment that takes much longer to spiritbind? It's not as though tier IV materia is or should be some ultra rare item. It's completely required to participate in high level crafting and gathering as well as necessary to make crafted combat gear relevant. It should take more time/ money/ effort than tier III materia, sure, but the current ratio is ridiculous and has had the unintended effect of drastically increasing the supply of tier III materia such that in a lot of cases it's cheaper than tier II.

Sorry, on topic. OP, I've always found that using level 45 equipment is as good as you can do. Anything 45-55 has the same chance of converting to tier IV, but 45 will SB much faster (I think about 50% faster in Urth's gift), is cheaper to produce, and easier to HQ if you're making it yourself and not a geared up crafter. Basically use the lowest ilvl equipment that you can that is 45+. This will probbaly be in the 45-50 range. To me ilvl 55 gear is just not worth it.

Pretty much this is what I do. Craft a bunch of 45-49 gear either for WHM or BRD, grab some friends and have them do the same, and go wreck Urth's Gift for a few hours. Don't bother with the meteor rings - just craft rings for yourself instead. The difference in spiritbonding speed is only about 3% for a full set. Get the company action if you can, and use a spiritbond potion. Level 45-49 equipment usually spiritbonds in 15-20 mins in Urth's Gift.

I like the cave in coerthas near boulder downs. level 49 mobs that respawn almost instantly and are non-aggro or anything. makes for very fast, easy spiritbonding I also prefer to use level 45-49 gear with the spiritbond potion and company action.

Out of curiosity though, if I do the level I and II actions together, do they stack?

Spare yourself the trouble and don't spiritbond anything above militia (i55). Things that are i70 or i90 can still turn into III materia, Lightning IV materia wooo.

Depends. Desynth items to get gryph, make full i70 right sides for almost free, put on That Which Binds Us 2 and a spiritbind potion, and run t4 5 times who are all doing the same thing. i70 has a higher chance to yield IVs, by how much I'm not sure.
