we need more details, please :Grin:
1. What happened to our Master Ball during the quest to fight the level 99 one? Will it be taken and returned afterwards, or does it stay in our bag but simply becomes unusable in the level 99 battle?
2. After defeating Heatran, when we go back inside, can we take more than 1 Pokemon or will Buck still restrict us with 1 level 60 or lower restriction?
Sorry for my english i will try give details.
1- you can´t caught hentran lvl 99 with master ball.
2. I have used pickaxe for get lvl in defeating all npc , after defeating Heatran , you can enter in vulcan with all poke don't have restriction .
3- Go in Heatran room and caught with masterball , ultra ... (Heatran lvl30) have fun.
Good Luck for everyone.
