Amplifying Adaptive Helm’s unique strength to make it a more powerful answer to the threats it’s meant to combat.
DAMAGE REDUCTION : Damage taken from repeated instances of a spell or effect is reduced by [15%] ⇒ 20%
Tanks have been struggling to deal with certain types of magic damage, specifically battle mages like Ryze or Cassiopeia who churn spell after spell into their enemies. Because burst mages have longer cooldowns - and rarely enough damage to one-shot tanks, tanks are less likely to die to them than they are the followup damage from marksmen. Battle mages - with their low cooldowns - circumvent that pattern by continuing to threaten tanks throughout a fight.
This leaves tanks feeling a bit underwhelmed with their available MR against battle mages. We can’t simply tune up MR items, however, without causing tanks to entirely invalidate other mages. Instead, we’re introducing Adaptive Helm to allow tanks some breathing room against persistent spellcasters. Tanks already have items that are tuned sustained damage from physical sources, with items like Randuin’s Omen or Frozen Heart helping them weather the storm. Adaptive Helm is a similar item for incoming magic damage.
