get all the dragon balls

u have to collect all the tier 2 dragonballs from the db event and wish it through shenlong

crit damage is valuable for fighters, moreso that it should be a given.
kaioken is honestly a preference choice to make but it does increase attk for both phys and Eng higher than ssj yet gives no extra hit rate, every time you stack the skill it adds your base crit numbers into itself, thus increasing crit with every cast.
if my phys crit was 30 and eng crit 12, then kaioken x1 it will stay that way, kaioken x2 would double it, and kaioken 3x my phys crit would be 90, and my eng crit 36.
i honestly think its a great skill to use on single targets, as increasing crit is the best thing u can do with a fighter class
not to mention the cooldown is much sooner than it would be for ssj, meaning its more valuable for dungeons considering if u die you dont have to wait almost an hour for your ssj to cooldown if u used it before going in, instead (with the cooldown buff) with kaioken u get about a 3 minute wait before u can use it again.

just get both
for ssj you dont need sp anyway
so use ssj when you want ot kaioken

i prefer kaioken cause my fighter have enought hitrate and also enouh dodge rate

I like Kaioken more because you don't have to wish for it. :P

How can you do that?!? O.o

if u have a healer
or with a tank cause with their naturaly big lp regen and big lp they can hold the kaioken without any lp drains ofc the ep drains faster so u feel that but u can get 2 ep7 chips and the drain will almost disappear

Thanks, but I was thinking more of how to do X3, X4 and so on?
While waiting for reply, I was all over this forum and bumped into a post where one suggested to just click multiple times on Kaio-Ken while being into one, to make it go higher - I cannot play for some time now, so it would be nice if anyone can confirm this.

How can you tell one which Kaio-Ken level you are, and what do you get with each SP invested into that skill?

to do x3 - x4 ecc just click more times on kaioken icon (the drain will go up, as well as your crit rate)

Kaioken is really hard to maintain, I just got it recently but I'm thinking of getting rid of it the drainage is so much more worse compared to SSJ. SSJ is a free skill with no SP needed sure it has a large cooldown but all you have to do is collect the 7 dragonballs and you get a free boost where as Kaio its 1-3 of your valuable SP.
