but sudden increase in 200 initiative with full battle armor rank lvl 4, how?

and can you tell me which of the above you told should give more initiative with less time?

Well i checked it and found his rune stones are unchanged, and charms also, but dont know about treasured tools or assist link cards, but can this much initiative be acquired from 2 lvl 8 refines and 3 lvl 5 refines while i have more higher refines?
