BUGFIXES

  • Cleaned up some tooltips with respect to percentages Fixed Malphite’s Energy Shield not benefiting from the Spell Power provided by Chalice of Power Fixed Space Pirates rarely causing additional coin drops when equipped with Giant Slayer Fixed an issue where a Kog’Maw’s attacks during Barrage could rarely become Trap Claw procs Removed the unintended orange glow that would play on melee weapons of units equipped with Infinity Edge Fixed an issue where Zephyr’d units could be hit by certain AoE spells like Teemo’s Satellite Traps

MOBILE CORNER

  • A few Team Planner bugs needed fixing. Xerath was lost in space for a bit. We found him and put him back in the Team Planner. We removed a few champions from the game in patch 10.12 but they hid away in the Team Planner. We found and removed them. Nocturne snuck into Tier 2 in the Team Planner. We put him back into his appropriate Tier 1.
