Teo Quest

I have cleared all the quests (including nana) except one reosoul at the tower but still no teo, how come, the blacksmith does have a red bubble though asking for a black gravios part (which i have no idea how to get) and normal gravios which i have in the inventory.

If I can remember, you have to kill Lao Shan first, before being able to fight Teo (I can remember I had problem to obtain it too the second time I did it, but when I succeded, I said "If only I knew it before....")

i just cleared all the quest including azure rathalos at the tower stage, so i should expect a lao shan quests first? i changed the season so many times but it does not appear. am i missing something?
the blacksmith does have a RED bubble though asking for a white gravios part and gravios parts that i don't know how to get (it is in japanese beats me).
the gravios parts that i don't know how to get is needed to upgrade a gravios armor, i know that for sure, the icon is in grey color.

beware cause this part could be the shogun gizami part. you'll only have it by breaking is shell

i have tried that breaking gizami shell in the swamp but no luck. when u mean breaking the gravios shell jaw would give way, leaving the upper shell right? I did it twice, the part is dropped or rewarded when quest is completed?

gizami in volcano area has a normal shell right, so must be in the swamp with the gravios shell.

you have to break the spinned long shell, not grav skull, or curved/flat shell. this is in reward (98%)

As I remember, you can get a better chance at the rewards if you successively break it shell 2 times or more within each fight.

add: I read the link on gizami, the drop rate improves with each time you break the shell.

i broke the (gravios) gizami shell twice, first the jaw gave in, 2nd the upper remain of the shell, then when it generates another gave it another whack and voila, there it is in the reward.

gravios is a peace of cake

Assuming you got the right item reward, did you clear the red bubble?
