General reminder that many changes cannot be easily datamined, such as functionality changes or bugfixes, and are not always final.

  • missile min travel time:  0.25s --> 0.227s
  • cooldown:  8s all ranks --> 9s-7s

  • tick rate:  0.25s --> 0.5s  (total damage over 2.5s unchanged)
  • now has a minimum range of 300 (max range unchanged at 600)
  • cost:  80 all ranks --> 80-100

Summoners

Barrier

• migrated to use data values instead of effect amounts
• shield:  105-411 linear for 2.0s  -->  120-480 linear for 2.5s

Cleanse

• migrated to use data values instead of effect amounts
• lingering tenacity:  65% for 3.0s  -->  75% for 3.0s
• cooldown:  210s --> 240s

Exhaust

• migrated to use data values instead of effect amounts

• cooldown:  210s --> 240s

Ghost

• duration:  15s --> 13s
• cooldown:  210s --> 240s

Heal

• technically a bugfix:  Heal has "850" cast range. If nothing is within 200 center range of the cursor, then it finds the lowest percent health ally within 835 --> 850 center range around you (i.e. the lockon search now matches the indicator cast range, but with minor gameplay impact rather than just a visual change)

Ignite

• migrated to use data values instead of effect amounts
• otherwise unchanged

 

 

Items

Lethality was always a proper stat for champions (in the sense that it's not a fake stat handled by scripts reusing flat armor pen) but it was never a proper stat for items (which instead had to grant you the lethality stat in their scripts). Now items can innately support the lethality stat, which simplifies their implementations. Unless stated otherwise, no item has had their actual lethality value changed.

There is also a new type of game calculation that inherently supports melee/ranged splits (previously work to simplify these was tooltip only, presumably this new calc also takes care of that tooltip fixup as well).

• impairing movement no longer applies an onhit heal over time for allies
• impairing movement now heals you and the lowest health nearby ally for 10-50 linear, x0.7 for ranged "users" (presumably this means if the Font of Life owner is melee/ranged then the ally gets x1.0/x0.7 regardless of the ally's range type?)

 

Inspiration

First Strike

• damage amp:  7% --> 8%
• base gold:  5 --> 15
• melee gold from bonus damage:  100% --> 50%
• ranged gold from bonus damage:  70% --> 35%

Future's Market

• removed

• new rune
• row:  1
• get 6% gold back when you purchase legendary items
• there's some other unknown data values for "150" and "-150" but not sure what they mean, could be minimum refunds? or maybe just leftover

Systems

minion xp splits:

• solo:  95% base xp
• group split evenly:  116% base xp --> 124% base xp
• this system has had a bug for a while where an index out of bounds check goes wrong, resulting in 5 recipients triggering a fallback behavior and actually splitting by 20% each instead of the intended 23.2% each
• interestingly, the data now defines a new split for 6 recipients, which would normally not matter, but might be sufficient to correct the mistaken belief that 5 recipients is out of bounds (of course, correctly the bounds check itself would still be preferable)

bounties:

• "death streak penalty":  0.2 --> 0.25  (no idea what this actually controls)
