oh, I thought the equipment set bonus is rather random too for the same equipment, no wonder said green drake set drop always give same set bonus

... Since I hardly spent on hunting, except to clear daily missions, I guess this is why it took me longer time by farming in pve quests... kudos for the info.
But yeah, agree wholly on the RGN part of equipment sub-stat is such an annoyance and it seems the chances are not equal for all the stats as I seem to get less desirable stats, eg effect resistance more so than any others... well, as time goes by, I coped with it on the monie issue, but still find it a nuisance how could unequip & changing equipment cost anything

(although this was not de 1st game did so)
As for skill enhance from awaken, I found it hardly noticeable for skills such as Cidd's which depicts use powerful skills when buffed with increased speed... so far I only own 2 heroes with such skill enhancement, the other being Mercedes... The game never clearly show how much dmg boost received from this enhancement

... you have any clue?
And last just need to find an active guild

...
i see u got Cidd there. not a bad chracter for PVP. Mercedes on other hand is not really a good choice as her skillset is not really that great i suggest you dump her for better unit. i believe you are talking about the awakening and not the skill enchantment under your character tab in lobby (coz they are both very different thing).
Usually third awakening aside from stat boost that you get it change the skill quite a bit and thus make it totally very useful sometimes is a game changes ( for example, Silk- her third awakening instead of giving speed buff to herself only while damaging and debuff all enemies has now change to speed buff to all allies while damaging and debuff all enemy) now you see this is big different as it speed up all your team therefore your team can produce better demage in shorter time. of course not all characters is as useful as one another that is why sometimes you see some of their awakening is actually not big of a changes (thus not so useful).
best way to promote your 4 star chracter to 5 star. there are two simple ways :-
Efficient way
Option 1:- obtain as many Gold phantasm as possible every week as you able to purchase them once every week , every week the game allow you to buy a gold phantasm in the shop and weekly mission also will give you a Gold phantasm if you manage to raise 2 white phantasm to lv 30.
after lving your 2 white phantasm to lv30 ( so now you have 2 gold phantasm and 2 white phantasm ) you can get your 4 star to 5 star.
Normal Way
Option 2:- if you dont have gold phantasm, then in your santuary (forest of soul) by improving the building mid to max level. you can summon 3 white phantasm at once (or you can use stigma to summon them instantly). therefore summon as many as you need to make 4 white phantasm to lv 30 and make them 4 star so your 4 star chracter can use it to promote themselves.
for a guild, try to join a guild that will open at least a exp scroll everyday so you able to get 10% extra exp everyday.
