[Kafriel]

Spoiler for Commentary on changes:

All champions have had their base movement speed increased by 25

Hmm, so Pantheon's ~350 MS (w/ quints+masteries) is now going to be a bit over 375 barefoot?

Lich Bane
No longer grants magic resistance.
Now deals magic damage equal to a base damage plus a percentage of your AP ratio.

This was quite overdue...lich bane dealing pdmg was just ridiculous when it's clearly a caster item.

Eleisa's Miracle
Does not grant Tenacity
Lowers Heal, Clairvoyance and Revive cooldowns by 20%
Gaining 3 levels with the item gives you the stats and passive permanently and the item disappears from your inventory.

What the fuuuuuck? Heal/CV CDR out of items, that's...new :O

Archangel's Staff
Upgrades into Seraph's Embrace when the Tears of the Goddess passive is fully charge.
Seraph's Embrace
Activate to shield yourself for 25% of your current mana for 2.5 seconds.
Manamune
Upgrades into Muramana when the Tears of the Goddess passive is fully charged.

Muramana
Toggle to deal a % of your current mana in magic damage on basic attacks and spells.

Epic buffs, my Urgot and Blitzcrank approve

Kage's Last Breath
Supportive Peel/Initiation Item
Recipe: Kage's Lucky Pick, Mana Manipulator
Keeps G/10 Passive.
Active: Target ally gets a 30% slow aura for 3 seconds - 60 second cooldown.

Like randuin's omen, but you can toss it on someone!

Mercurial Scimitar
High End Magic Resistance / Attack Damage Item
Recipe: Quicksilver Sash + B.F. Sword
Active: Cleanses all debuffs from your character. If your character is melee, he gains 100% movement speed for 1 second.

ROFL, most unbelievable combination ever

Ohmwrecker
High End Siege Item
Recipe:Catalyst + Chain Vest
Active: Disables nearby enemy towers for 2.5 seconds, preventing them from attacking.

Towerdive awesomeness when used in succession.

Hurricane
Ranged-Only Area of Effect Item
Recipe: Dagger + Recurve Bow + Dagger
Passive: Your shots fire two secondary ghostly bolts that deal X + 50% of your attack damage to nearby targets. These cannot critically strike but apply on-hit effects.

Ranged-only? What about hybrid champs (Kayle/Nidalee/Jayce etc.)?

Sword of the Divine
Rapid Burst Attack Damage Item
Recipe: Recurve Bow + Dagger
Active: You gain 100% attack speed and 100% critical strike for 4 seconds or 3 critical strikes - 25 second cooldown. This item gives no attack speed while on cooldown.
Passive: Kills and assists halve this item's cooldown.

This+youmuu's= raging Trynda.

Mikael's Crucible
High Tier Supportive Item
Recipe: Chalice + Sapphire Crystal
Passive: Increases mana regeneration based on missing mana.
Active: Removes stuns, roots, silences, slows, fears and taunts from an ally and then heals them for X + Y% of their missing health - 3 minute cooldown.

Best.Support.EVER.

This is how you freshen up a game, change a TON of items but also offer increasing expertise on particular roles while expanding the end-tier trees. Having items specifically for pushing with casters (who generally suck at pushing without LB) makes one think twice before going the standard AP route. More active support items diverge from the passive aura whores and active ADC items may make certain right-click-to-win champions more fun to play as. New upgrades make forsaken items an attractive choice once again and mixing some low-tier items into new stuff will help bruisers and tough casters fulfill their roles with more ease.

Really looking forward to everything that is to come, though I probably won't get to play again for some time.
