i had reply typed for other thread for weapon skill system but post here seem better idea

weapon skill works as % modifier applied to characters of correct element.

1- all weapon skill goes to 20
2- increase in required weapon skill fodder for each lv is linear increase
3- R give 0.5% to 10%
4- SR give 3.5% to 13%
5- SSR give 6.5% to 16%

it much simpler system than granblue that has 3 types of weapon skill (normal, magna, unknown) which multiply each other. here it only 1 type, where u add all and that is total bonus.

for example, after farming Lightning Disaster for a while i have
lightning strike axe slv9, full uncap (using as mainhand)
lightning strike axe slv6
lightning strike axe slv3

damage bonus for lightning characters is 7.5 + 6 + 4.5 = 18% bonus damage for all lightning characters. but this grid is only starting. if u had 10x lightning strike axe even at low slv like 6, that is 60% bonus ATK. full SR grid at slv20 is 130% bonus attack. full SSR grid is 160% bonus attack but is impossible unless u rich oil baron.stacking atk skill on 1 element and using kamihime for that element is how to progress. summon also encourage stacking single element. however u may still need debuffer, buffer or healer of other element to survive. Beelzebub is good for ATK + DA + rampage buff for all element.

if u not counting event for now which will give SSR weapon, the way to progress is SR weapon drop from raid. only from mvp or host chest for normal, and all chests in expert raid with higher chance in mvp or host chest.u want to have as many 0 limit break atk weapon as possible early so u can start leveling and skilling them, but also 1 fully uncapped for mainhand so ur burst damage is higher. the hp weapon are useless compared to atk but maybe still keep 1 each fully uncap for use as mainhand for other souls.

[strike]for skill up, when ur sr item is skill level X, u need X r weapons with skills. for example if SR slv3, u need 3 R to rank it to slv4 at 100% success rate. don't ever upgrade if not 100%, u will learn how to cry when fail 90%.eventually u will also have additional SR like the weapons with HP skill that u do not need that u can also feed to ur main weapons. save them for higher slv skill ups.[/strike] info repeated from op

sorry for long explanation and hope it not confusing. english not my first language.

about what to focus or split elements

there are 2 kinds of progression in the game. the raw stats and the multipliers
-raw stat dependant on your kamihime rarities and level, weapon rarities and level, eidolon rarities and level. since higher is better, whatever ssr u have is best, but after a while the weapon and eidolon u can farm will have higher raw stat since u can uncap them
-multiplier dependent on eidolon aura from both ur main eidolon and friend, and weapon skill. multiplier requires u focus on 1 element which is opposite of raw stat where u just taking the highest raw values u can get

i think even free player benefit more from going on one element. however, due to rng and gacha ur element may be decided for u, and u can only build on what u get to make it stronger.

even though game is much simplified compared to granblue the power progression has very large priority on weapon grid, and the only way to farm weapon grid is to farm the disaster raid bosses for atk weapon skill and build as many of them as possible. as mentioned in previous post, u can stack up to 160% bonus ATK from a completed grid although this will take a very, very long time and in the meantime u will get 1 or 2 ssr from events or lucky rolls.

when ur grid is decently progressed and u have matching friend summon u can hit hard. example right now with my lightning grid, 2 ouroboros 40% summon from me and friend and about 30% total bonus from weapon skill, my R lightning tank hit harder than Artemis in same party.

for opposite element, for free player i suggest the opposite and focus on raw stats only, which mean equip all your highest level weapon, don't worry about weapon skill and then put a decent eidolon bonus.

for example i focus on lightning grid with weapon skill multipliers development as long term project, but for difficult wind enemies i also build a raw stat party with fire characters.

sorry for bad english again...

last post for now...

firstly i am sorry i made mistake in previous post. i meant to say farming the disaster raids for sr weapon and eventually all skill level 20, ur total bonus will be 130%, not 160%

2 more things about focusing 1 element from wind/water/fire/lightning

- u have innate advantage over 1 element, example lightning fighting water enemy
- u have innate disadvantage to 1 element, example lightning fighting wind enemy
- u have innate neutrality to 3 elements, example lightning fighting fire, light and dark. actually light and dark have slight advantage but negligible.
- u have actually innate disadvantage to same-element, because debuffs are very hard to land, example lightning fighting lightning.

debuffs are very strong in this game, and it seem it copied granblue regarding same element debuff rate penalty. if u land ATK/DEF debuffs on hard enemy, u get insane advantage because it hit half as hard and u hit twice as hard. therefore same element fighting is disadvantage.

if u build 1 grid u will have easier time on 5 of the 6 scenario above.

lastly u can focus light or dark as first primary element but after playing granblue i dont recommend because it is SLOW to build and u go mad...
