I won't list the affixes one by one. Too many, I can't remember after playing for so many years. What kind of affix is good depends on the situation. For example, some affixes add all the skills of a character, such as "angel's", 1 witch skills, "archangel's", 2 witch skills, "witch hunter" and 1 or 2 assassin skills. I forgot, I forgot the rest of Summoner. These are all very good. And "Whale's", plus 100 health. "Prismatic" amulet, which increases all resistance. These are all very good. What is good depends on what role you play. Glad to see what you need.
Ilvl is a project level. Different monsters have different levels, and the same monster has different levels under different difficulties. The level of the monster determines the level of the dropped item. This ilvl is also related to your role level. When you go to the store to buy things, the ilvl of the items you sell is in the range of (your role level +5~ your role level -5). On the whole, this is of little use. But there are two situations that need this. One is that when you are MF, the grade of some special items is certain. For example, the claw in the assassin's suit is called "the mark of Natalia", and its specific ilvl is not clear. If you want to hit this equipment, you have to go to K some monsters with a higher level than this ilvl (or something similar, I don't know) to get it.
Another use is when you make handmade products. This is ilvl, the higher the better,
Ilvl = 1-30, there is a 40% chance of getting 1 affix, and the chances of getting 2, 3 and 4 affixes are all 20%.
Ilvl = 3 1-50, there is a 60% chance of getting two affixes, and the probability of getting three or four affixes is 20%.
Ilvl = 5 1-70, there is an 80% chance of getting three affixes, and the probability of getting four affixes is 20%.
Ilvl = 7 1-99, and there is a 100% chance to get 4 affixes.
Of course, if you want to make good handicrafts, look for the items with the highest ilvl. K Barr, the hardest thing, the item he dropped was level 99, which is the highest level.
There are too many things in the dark, and these are just a few. If you have any questions, please contact me.
