your welcome =D
When you finally regain control of Roxas after all the cutscenes, talk to
Demyx twice to get a Shining Light Shard [光かがやくかけら]. New entries
will be added to Roxas' Diary as well. Talk to Saix and he'll have 4 new
missions for you. I'll cover them in order from 16 to 19.
Mission 16 - Agrabah
Your goal is to kill all 7 Fire Plants -- there are 2 at the Palace Gates;
2 at the Bazaar, and 3 at the Palace Walls . Begin by picking up the ARMED
GEAR + [アームドギア+] from a chest at the gates, then move on to the next
area. There, grab take the POTION [ポーション] and ETHER [エーテル] from
both chests.
Come back later when you have High Jump to claim a DIAMOND [ダイヤモンド]
from a chest in the Bazaar.
For the targets at the Palace Walls, you'll have to kill the Barrier
Master first, since it casts Protect on the plants. Hit it to knock
the book away then spam the creature with magic. Take out the flowers
afterwards.
Back at base, talk to Saix and he'll give you a LV2+ [LV2プラス] link
panel. All the level up panels you place in the link area will boost your
level by 2.
it is that part
