Update 15 is live! Sorry guys, I had to progress through Reborn a bit more to be able to keep going..
Note15: After having progressed through Reborn a little bit more, I've made a little update featuring the things now available to the player after defeating Shelly and obtaining Rock Smash. Mining Kit location is explained as well. The Drifloon event + scenes are added, including the reward for completing this side-quest (additional floor in Dept. Store). Final thing added was encounter with Fern in the Grand Hall. Next update will feature encounter with Cain and continuing storyline.
Shade gave me one helluva challenge and took quite some time to get past with my current line-up..
For anyone wondering what I'm using in my playthrough, my team is currently as follows;
Silver (Greninja) - Ability: Protean - Night Slash / Water Pulse / Round / Grass Knot (Level 42 I believe)
Fezz (Growlithe - Ability: Intimidate - Crunch / Fire Fang / Flamethrower / Rock Smash (Level 41)
Shirinui (Helioptile) - Ability: Dry Skin - Parabolic Charge / Bulldoze / Charge Beam / Grass Knot (Level 39)
Tempy (Azumarill) - Ability: Huge Power - Aqua Tail / Bounce / Double-Edge / Superpower (Level 43)
Pow (Kirlia) - Ability: Trace - Psychic / Charge Beam / Calm Mind / Magical Leaf (Level 39, future Gallade)
Fruity (Noibat) - Ability: Frisk - Tailwind / Roost / Shadow Ball / Air Cutter (Level 38)
Currently at Pyrous Mountain, training up to get ready to face Cal.
This is a very reliable squad who have yet to completely fail on me in terms of scouting for moves and items to get this guide as accurate as possible, though I do have quite some help from outside the game (Mikzal, Tempest and Blind Guardian mainly), helping me with things I've missed. I greatly appreciate their help, but I also appreciate all the comments you guys have made, thanks again!
