the top is for play DMM directly on site, and ignore api link, not all are translated

2nd one use DMM site and api link, and translated

try remove and reinstall the extension
else can ask the solutions to devs at their home page

your first goal should be unlock your 2nd/3rd/4th fleet asap, in order to expand your upkeep.

For Kongou sisters farming, try to get to 4-1 & 4-2 asap.

World 2 do drop Kongou class BB
btw 2-4 is bane for all newbies

i last time took quite a long time to get the kongou sisters
need battleship to clear 2-4
other than drop (i think 2-4 drop it) or construction... it's all about RNG

i think 2-3 is not 100% boss route, right? even certain ship can increase the chance of go to boss node...

should be no problem since u have 2 BB (and nice BB too, i got them quite late, probably when i unlock world 3 )
maybe need some level + modernize

2-3 should be no big problem once u have some level
can get some ships while u farming, for some modernize and some equipments too

maybe u can try just use 1 of your BB, take the gun of 2nd BB and equip on the BB that u use
(i think u only use 1 red gun for both of your BB, right?)
i remember last time i was problem on 2-4, farm quite some time only got 4 BB
and only get my last kongou class BB at world 3 for 4th fleet...

normally double red gun will be higher chance for double attack

the gun mount attack plus seaplane is it something like the seaplane fly, then show u the name of your gun, then one big damage?
(normally one big damage but sometimes may small damage or even miss)
this one mostly will happen if u equip 1 red gun + 1 yellow gun + seaplane

and for sparkle, mostly i want sparkle for evasion...
i think maybe affect accuracy but should be not affect this special animation attack...

it's up to u, CV or CVL...
normally CV more planes but CV use more fuel/ammo...
u should use the same plane again and again, the plane itself will become better if u use it repeatly

Chitose and Chiyoda are not bad if u train them and remodel at level 12 (after level 12 they can remodel again and become CVL)
they have nice equipments u will use it in future

don't worry too much about world 3...
u should have some nice ships if u can clear 2-4

go finish e1 easy if u can worth it for rare drop clear map can be done anytime

ya, it is something like plane leveling, the plane will become better as u use it more and more...
quite a big difference if all your planes have highest level

as kenjixx post here, maybe u can try e1 easy if u have the resources (today is last day or to be exact, until morning 8/12/15)
i play hard also feel like nothing unlike e5, i play easy also retreat quite a lot

or at least maybe u can try first few nodes of e1, maybe u can get some ships that u don't have

ya, the event one
the red color that u found it at right side corner of somewhere u choose world 1/2/3...

u mean ship drop? normally event map have higher drop rate than normal map

for E1, u need to use 12 ships instead of 6...

If nothing goes wrong, normally the server will back online at JST 1700 (Malaysia time 1600 => 4 pm)
