What do I need to in order to get 100% in Skylanders Giants?
Besides the Skylanders Giants game disc, in order to get the platinum trophy in this game you are going to need: A Skylanders "portal", an AIR type Skylander (swirl symbol), a LIFE type Skylander (leaf symbol), a UNDEAD Skylander (skull symbol) and a GIANT Skylander. The three figure game pack comes with all of these items but there is also a "Portal Owners" pack that only includes the game disc and Tree Rex the Giant LIFE type Skylander.
Step 1 - Complete the game on any difficulty
Simply play through the game on a difficulty of your choosing, I recommend Cyclops Crusher (Medium) because you will need to have some skills to be able to get through Nightmare difficulty. During this step you should be able to knock out the majority of the trophies including all but one of the story trophies and 80% of the level specific trophies. I recommend sticking to one Skylander for this playthrough in order to get Upgrade Uniter, and To the Max. Keep an eye out for the ship parts and story scrolls for Seeker Adept and Hint Scholar. Also go ahead and go for Great Gladiator! during this playthrough as it will help level up your Skylander faster.
Step 2 - Clean up
I put this as step 2 as it is a fairly quick clean up and is easier done on your low difficulty save file rather than on Nightmare. You are going to want to get Completionist, A New Hero, Skystones Strategist, Soul Surfer, and Clean Jersey. There is a good chance that you may of missed some level specific trophies like Keepin' Cool, Freebot Isn't Free, Pedal to the Metal, Autogyro Pyrotechnician, and Talker in a Strange Land as well and now is the best time to get them. After this step you should have every trophy except Nightmare Avenger, Spend that Loot! and the Platinum.
Step 3 - Nightmare
Go to the main menu and start a new game, you will notice that there is a new difficulty called Nightmare unlocked. Play through it until the end and Nightmare Avenger
will be yours. You will be able to easily get Spend That Loot!
during this step as well if you are playing with your fully upgraded level 15 Skylander. Nightmare difficulty is much harder than easy mode but it is still a fairly easy game. Try to avoid any unnecessary fights and areas to speed this trophy along. Make sure to move carefully while in battle, in Nightmare difficulty your Skylander can get KO'ed in a single hit at times. Having a good amount of Skylanders probably around 4-5 will make this playthrough a little easier, think of each Skylander as a extra life. If your main Skylander gets killed cheaply you can finish the level with a different one, which saves a lot of time by not having to replay any levels.
While it is recommended to have plenty of Skylanders this game is very do-able with just a couple, and you are not required to have more than one. After defeating the last boss you will unlock Nightmare Avenger
and NO WAY!!!!!!!!!!!!!!!!!
