Predecessor Builds > Gideon > Gideon Build (Mana Bomb)
When picking Gideon you want to both deal a lot of damage and also have some sick ult moments. With that in mind you really can build him with the majority of MP items. With this build you will deal consistant damage and have quite a bit of sustain.
Starting Crest; always go for Magician Crest, with the options of either Epoch (for if the enemy team has heavy hitters and you want to not take a bunch of damage post ult or you are in a pickle and need a couple seconds for your team to get to you.) or Soulbearer (for if the enemy team is a heavy burts comp, since you will naturally have high total mana throughout the game you will get to 400+ shield.). Running with Epoch is going to be the normal, except in those high burst games.
Item pathing; Rushing Alchemical Rod first is crucial, it allows the ability to increase your mana, which in turn allows you to clear waves more. However you wont be finishing the item for a bit. Going into Orb of Growth second allows you to get the health sustain and even more mana. Once that completes going into your first main damage item; Megacosm, which allows you to deal %Hp damage and also get 70 MP and you guessed it more mana. You are probably like whoah this guy likes mana, well heres the fun part; Finishing Azure Core not only do you get the items stats, once you have 400 stacks on the item you recieve 3.5% of you total mana as MP. Which boosts you up so much. Following those three items is really situational; Do you need magic pen (Caustica)? Do you need anti-heal (Tainted Scepter)? do you need sustain (Spirit of Amir or Spellbreaker)? Now if you dont really want to run those items or you prefer maxing damage; Finishing your build with these items will Cap out how much damage you deal; Wraith Leggings, Oblivion Crown.
