How to fix all three support items
Relic shield: Healing now halved by any ranged champion that has purchased targon, shielding power now scales with max health.
Spellthief: Tribute gold and damage disabled when a minion is hit, disable duration three seconds, this item is meant for poke champion or those looking to play aggro.
Ancient Coin: Coins are only dropped when an ally is present with x range, coins only drop when minions are around anyways and anyone who takes coin is most likely a very passive laner like Soraka, Janna etc who will most likely spend their entire game next to their ADC.
, get no procs for your harass for the next few seconds.
