New Item: Scroll of Secrets
Inspired by "Agahnim Scepter" from DotA 2, it gives champions empowerments specific to them. This item may require a lot of work, but could go a long way in distinguishing Mages or Mage Sub-classes along-side upcoming reworks.
Scroll of Secrets
+50 Ability Power +20% Cooldown Reduction +50% Base Mana Regeneration ACTIVE: Reveal Secrets - Your champion reads the Scroll and gains forbidden knowledge, empowering one of their spells to new heights. Duration, 30 seconds. Cooldown, 120 seconds. [Champion Name] - [Ability Name]: [Additional effects]
Notes and Theory: -Ability Power is low compared to other AP items to compensate for increased powers in the active. -Providing Mages with another source of 20% CDR -Mana Regen completes this as a "cast lots of spells" item, but is not optimal (100%) to keep other M. Regen items attractive -Empowered Spells gated by an active with Cooldown, because windows of power and opportunity for opponents are important in League. -Stat bound to mages, so not every champion has to have a buffed spell, and to help differentiate the mage class. -Offers a new lever in champion reworks or for balance issues.
Champion & Ability Examples; These are all just theoretical for example and not necesarily balanced or what should be on the item.
Ahri - Fox-fire: Creates 5 fox-fires instead of 3. Annie - Summon Tibbers: Tibbers is larger, with a greater spell area of effect. Elise - Coccoon: Recast the spell to tug a Cocooned enemy a short distance toward you Fiddlesticks - Crowstorm: Cast time halved Karma - Mantra'd Inspire: Shield explosion deals damage to enemies nearby :^) Karthas - Requiem: Reveals targets Lux - Light Binding: Continues for 3+ targets but applies reduced root to each one Morgana - Black Shield: Grants +50 Magic Resist while it holds
etc.
