Newbie katana

So i made a new katana character, and frankly im dumbfounded on how to build it, ive watched youtube vids and tried searching for decent build guides on here but to no avail. I could really use some advice for doing one.

 

full str and 38 crt, rest dex(more stability more cdmg) or
full dex and 38 crt, rest str(more damage)
dex is more popular

weapon - element katana for more damage but cost a fortune as you need 6 element katana + 1 fullcrit non element katana
or you can use a7cdcrcr15/16 or cd7cdcrcr15/16
xtall: odelon and ultimate machina

armor - fullcrit+15 or 16
xtall: super death mushroom and ornlarf

add gear - fur hat for +1k hp and +10crit
xtall: baphomela and odelon

special gear - dextal iv
xtall: odelon and goovua or deniala for more ampr

as for skill

katana skill tree:
tenryu lv10(main dps)
magadachi lv1
zantei lv1-10(optional to activate tenryu buff beside magadachi)
bushido lv10
two hand lv10
shukuchi lv10
kairiki lv10

blade skill tree:
warcry lv10

halberd skill tree:
quick aura lv1(filler for combo)

dual sword skill tree:
godspeed lv10
flashblast lv10

shot skill tree:
quick draw lv10
sneak attack lv7 (optional if you need to lower aggro, isnt really necessary)

survival skill tree:
hp boost lv10(optional if you need more hp)
mp boost lv10(optional if you need more mp)

support skill tree:
recovery lv1(manually use it before kairiki to prevent burn)


combo :
opening :
manually use recovery
pulse blade> kairiki(save)> flashblast(swift)> warcry(save)> tenryu(swift)

then use magadachi and prevent to not being hit by target, or use zantei to parry attack

when tenryu buff become 30s, use tenryu> auto attack> tenryu> auto attack and so on..
