Item idea

Tunic of Occult: Build path- Giants Belt, Spectres Cowl, 600g Stats- 40 MR, 450 health, 150% Health Regen Unique Passive- The first magic damage that hits gives %MR that scales with the damage dealt (1% per 100 damage) (45 sec cooldown) Unique Active- Upon activation, all magic damage taken in the next 5 seconds converts to ability drain (Magic damage is calculated as a percentage of your health) 120 second cooldown

The idea behind this item is to give bruisers a way to survive through a fed AP Assassin or marksman. Maw gives a good passive, but gives no health. In certain circumstances, the Health would provide the ability to get through an assassin, and the ability drain allows the bruiser to heal back up. In matchups like say, Darius into Leblanc, if she is fed enough she can just kite him. However, with this item, he gets the MR to disengage, and if she overextends for a kill, he can heal himself for the damage she has dealt and turn a fight around. In other matchups, such as say Jax or Irelia into Teemo, the item can be activated so as to give them a fighting chance to win once his blind is down. The item fills the void of an item for tanks/fighters who don't work well with Maw and or need more defensive stats than Maw would provide. Champions like Riven don't always make use of Spirit Visages Passive, nor does she receive full gold value from Abyssal. And adaptive helm has less health, more MR, but is more suited for dealing with consistent damage from poke threats compared to Tunic of the Occults ability to deal with high burst damage. The other major component is that Bruisers don't fair well when running into a teamfight as they can get poked out or have to run through an onslaught of damage. This item gives them the necessary stats to get into a fight, stay in the fight, but without overloading the champion with too many base stats outside of the actives.
