#1The mysterious force or called in the game "the unseen force", will attempt to blow you out of the dungeon if you take too long on a dungeon's floor. Fortunately, the unseen force Resets everytime you find and go down/up the stairs. Also while inside a dungeon, you are working against a turn-based time limit, meaning one step you make counts as a turn. So don't be a "slowpoke" and try to find the stairs quickly! I'm also not sure it even reveals what is making the unseen force!
#2 I have pikachu as me and I named him kirby! Plus he is super strong being only at level 36 with my partner torchic! To get pikachu as a starter, you want to choose answers that show you as an "impish" type. I can give you answers that are considered impish: 1st', the test? Ignore! 2nd, find wallet? Is anyone watching! 3rd, the pitfall? Yes! 4th, pranks? Yes! 5th, bully? Heckle! 6th, puns? Love them! 7th, pitch black room? Clean it! 8th, others watching what you say? Yes! 9th, have dreams? No! 10th, gotten into a fight? Yes! 11th, have you slowed down? No! 12th, see a person you like? Pull a prank!
These are in fact the only questions that have impish type answers! Hope this helps!
