Cost of starting support items increased.
The current cost of support items lets support players mitigate a pretty high amount of poke through potions, which makes trading feel more ineffective than we'd like.
Nomad's Medallion Targon's Brace & Frostfang
TOTAL COST : 850 gold (unchanged)
COMBINE COST : [500 gold] ⇒ 450 gold
TWISTED TREELINE These changes also apply on Twisted Treeline.
Bandit passive removed. Movement speed added to Ancient Coin line of items. Many other changes.
These are just the same changes these items have gone through on Summoner's Rift over the last 2 patches.
All Support Items
BANDIT No longer grants gold when nearby enemy minions are killed by allies or when attacking enemy champions
Timeworn Relic Shield
HEALTH :  ⇒ 50
The old support items (without wards) will remain on Twisted Treeline.
