Item balance changes

Shadowflame:

  • Bugfix: Now deals the correct damage (was reduced by remaining MR an extra time), but still applied in a bugged way via a separate instance.

As a side note, Maw of Malmortius has a new data value stating "8% Omnivamp" which shows up in the League Client tooltip, but in-game the effect after the shield is triggered is still at 10%. Unknown what was or is the intend regarding this one.

Tooltip fixes:

  • Sterak's Gage tooltip now clarifies that the shield decays over the duration.

  • Rell E and Urgot E tooltips now include their stun durations.

Some stuff relevant for challenges:

  • Qiyana and Renata have had their missing ability traits added so should show up in synergy challenges now

  • Rell:

    • secondary class changed from nothing to support
  • Syndra:

    • secondary class changed from support to nothing
