1, the income from jewelry and leather making is the main attribute of 320. If you subtract 180 intelligence from 500 intelligence, the income will still be 320. It is the same as jewelry. Actually, it's better than jewelry. (Jewelry can be inserted into two jewels of the main attribute of the gem 320. However, taking up slots, the two attributes of fire method are greater than 1 intelligence income, so it is better to do this.)

2 & amp3, fire method attribute heap crit. Jisu 3039, this threshold is more suitable.

4, troll 5% beast damage is useless to boss.

Finally, many concepts above your question are biased. The understanding of occupation is too one-sided.
