1. 4* gathering: volcano area 1,2,4,5,6,8,9,10
(Never got one from area 3)
2. Chameleos carves and reward
3.Pokke farm:Bomb mining and MP+2

Maybe i missed other possible ways to obtain them but those are my experiences about
obtaining dragonites

where do i find a lightcrystal ore??
and how to defeat tigrez???

Lightcrystal can be obtained by mining at the swamp (Area 3 & 9) or just kill some
Gypceros (Break the head for more chances to get Lightcrystal)
How to defeat Tigrex? It has been answered in previous questions.

you can give trenya 200 pokke pnts. and tell him go to jungle or very hard to find at
mountain

almost everywhere in the volcanic zone

i find area 4 works best for me in volcano

the dragonite ore can be easily obtain in the pokke mine send the cat in wiv a large bomb
+ and willnot believe what you get out of there ive had union ore nova crystal, dragon
heart and many more but what made me laugh is if you sell the dragon heart it goes for
200k a ruby
