Idea for Health Regen as a component item
+20 health regen per second
######This item is equal in value to 
after 5 seconds of regen
This item kind of seems like an overlap with Giant's Belt, but I really liked the potential combinations and changes to existing combinations it could create.
#Regeneration Combinations
- +
= 
(AD + MR changed to Mercurial Scimitar, see below) - +
= 
-
- Attacks deal 50 bonus spell damage on hit and steal 3 MR, stacking infinitely (debuff stacking infinitely too).
-
- Alternatively: Attacks deal 50 bonus spell damage on hit. While below 50% health, attacks heal for 50 health.
- +
= 
-
- Dealing spell damage heals the weakest ally by 20% of the spell damage dealt. (possibly bonkers on Veigar...)
- +
= 
(Health + Mana changed to Rod of Ages, see below) - +
= 
- +
= 
-
- Surrounding enemies take 25% increased spell damage (stacking these increases the radius rather than amplifying the effect).
- + = Red Buff (Health + Armor changed to Sunfire Cape, see below)
- + Spatula =
-
- This champion deals 20% less damage but takes 40% less damage. (each stack is multiplicative, so 20/36/48.8% and 40/64/78.4%)
- + =
-
- +100% increased healing from all sources.
#Changed Combinations
- + =
-
- This unit is immune to control impairing effects (CC).
- + =
-
- On ability cast, this unit becomes invulnerable and untargetable but unable to move or attack for 2.5 seconds.
- + =
-
- On ability cast, heal for 100% of mana spent. Increases mana generation from damage taken by 50%.
- + =
-
- Nearby enemies take 40 spell damage each second.
