AP Item Concepts
I am going to give ideas for new utility mage items (yes can be used for supports as well, obviously), a disengage item (this will be classified under a strategic diversity item), a new AP/MR item for mages so the new Abyssal Scepter can come into LIVE for the tanks and bruisers, and finally new AP and CDR items most likely building out of Fiendish Codex mainly for options and customization.
NOTE: My ideas will be based on the AP items changes as well.
[001; ap, cdr, utility buffing]: Recipe: Needlessly Large Rod (1250g) + Fiendish Codex (820g) + 430g = 2500g
Statistics: +100 Ability Power +10% Cooldown Reduction +UNIQUE Passive: Your shields and heals are increased by an additional 60(+15%AP) (one-third of this effect for multi-target shields and heals). +UNIQUE Passive: Your slows and hastes are increased by an additional 5%(+2% per 100AP); if a slow is already 70% or greater then it cannot be increased further from this effect.
[002b; low tier item, ap and health regen]: Recipe: Amplifying Tome (435g) + Rejuvenating Bead (180g) + 185g = 800g
Statistics: +30 Ability Power +100% Health Regen
[002c; low tier item, ap and mana regen]: Recipe: Amplifying Tome (435g) + Faerie Charm (180g) + 185g = 800g
Statistics: +30 Ability Power +50% Mana Regen
[002; ap, regens, team play rewards, disengage and supporty]: Recipe: 002b (800g) + 002c (800g) + 002c (800g) + 600g = 3000g
Statistics: +100 Ability Power +150% Health Regen +100% Mana Regen +UNIQUE Passive: Whenever you haste, shield, or heal an ally champion other than yourself then restore 10% of your missing Mana (1.5 seconds cooldown). +UNIQUE Active: Cleanse all stuns, slow, roots, or snares on the target ally champion or yourself and knock-back all enemies surrounding that unit (150 seconds cooldown). [Range 800 units; knock-back AoE 600 units]
[003; ap, mr, spell 'absorption']: Recipe: Negatron Cloak (850g) + Blasting Wand (850g) + Null Magic Mantle (500g) + 600g = 2800g
Statistics: +60 Ability Power +80 Magic Resistance +UNIQUE Passive: Absorb spell damage storing up 40% of all spell damage dealt, before resistances apply, to you up to a cap of 40(+130%AP); you cannot store up spell damage while this item's active is on cooldown. +UNIQUE Active: Unleash a powerful bolt of magic in the target direction dealing magic damage equal to the value you stored up to the first enemy champion struck (15 seconds cooldown). [Range 1200 units]
[004b; low tier, ap, mana]: Recipe: Amplifying Tome (435g) + Sapphire Crystal (400g) + 65g = 900g

[004c; low tier, mana, cdr]: Recipe: Sapphire Crystal (400g) + 200g = 600g

[004; ap, mana, cdr, cost reduction]: Recipe: 004b (900g) + 004c (600g) + Fiendish Codex (820g) + 480g = 2800g
Statistics: +80 Ability Power +650 Mana +20% Cooldown Reduction +UNIQUE Passive: Reduce Mana costs by 30%.
[005; ap, cdr, reducing cooldowns] (Mana Champions Only): Recipe: Needlessly Large Rod (1250g) + Fiendish Codex (820g) + 930g = 3000g
Statistics: +100 Ability Power +20% Cooldown Reduction +UNIQUE Passive: Increase your Mana costs by 15% to cause your spells to reduce the cooldown of all your spells by 1 second whenever they deal damage to an enemy champion (0.25 second for Multiple Target and Damage over Time spells).
Spells that do not use Mana cannot have their cooldown reduced from this effect.
