Free Swag is available with a casual google search of "League of Legends free Promotional Content"
For NA: Garen + his 975 skin Tristiana and her Riot Girl Exclusive Skin

Hextech Chest: at level 5 you will get 2 free Premium Hextech chests with VERY SPECIAL LOOT you won't encounter these again even when dealing with other premium chests. Chest 1: Ashe + Garen shards and just enough blue dust to craft them. + 1 skin for ashe or garen (from their below 520 rp skins) Chest 2: This one is very important: 1 975 valued skin shard (store, legacy, promo content, basically any 975 skin normally available in a chest) for a champion YOU OWN, if they don't have a 975 skin or you already own them all you will get a random skin valued at 520 RP or so or some other random skin Its very important you own a champion if you don't like to gamble eligible for this skin shard. or pick a champion you want to mastery rank 7 on that has a 975 skin. Most of the best looking 975 skins are Holiday skins so go check those out on the League of Legends Wiki. You will also get a shard for a random Ward Skin and enough dust to make the ward and skin most likely.

ONLY own the champion you want the 975 skin for (many champions DO NOT HAVE ONE or have only one 975 skin, other champions like Annie have 6 or more) check the league of legends wiki for the champion you like and what skins you can get at 975 value.

Read the League of Legends wiki.

DO THE TUTORIALS the game offers you it teaches you literally everything about the game except micro stuff. You get +492 bonus IP and a BUNCH of bonus XP (around +150-190) Do intro bots to level 5, max ip and xp gains, Buy a 450-3150 champ with your ip for the above box (or wait) Do beginner bots to level 10 max ip and xp gains and good place to learn mechanics.

Try out Twisted Treeline once you hit lvl 7 it is much simpler to play but more challenging and the AI is very difficult.
