HEROES
===============
- Axe: Fix to the AI ignoring everyone but Axe in earlier waves. Later waves will be corrected once they are reworked to the new AI.
- Pangolier: Shield Crash now grants scaling damage reduction per unit hit, up to a maximum of 80%; creeps give less damage reduction than creep-heroes.
- Shadow Fiend: Presence Aura Affect Buildings talent to Presence Grants Allies Armor.
- Shadow Fiend: +25 Attack Speed talent to +200 Agility
- Shadow Fiend: Every unit killed increases the armor reduction for a duration. Creep-heroes reduce it by more.
- Gyrocopter: Buffed Flak Cannon's total attacks.
- Gyrocopter: Buffed Aghanim's Scepter.

HEROES
===============
- Anti-Mage: Counterspell reworked, no longer blocks spells from affecting him for a short duration. Instead, grants Anti-Mage a barrier that blocks spell damage. While the barrier is in effect, Anti-Mage is Debuff Immune. The barrier lasts 8 seconds and after the first 1.2 seconds starts degrading at an accelerating rate. Casting Counterspell again resets the barrier, but does not reset the degradation rate.
- Anti-Mage: Shard causes Counterspell to block all forms of damage.
- Weaver: Fixed Shuckuchi
- Weaver: Rescaled Shuckuchi cooldown for the new talent.

Fix to Enrage not properly being removed with damage

HEROES
===============
- Lifestealer: Feast reworked, no longer scales off of enemy health, instead gives Lifestealer bonus damage and heals him for a fixed amount every attack landed.
- Outworld Devourer: Buffed Arcane Orb, fixed Astral Imprisonment not giving mana and normalized Sanity's Eclipse base damage (overall more damage).

techies fix
implemented disable help

GENERAL
===============
- Dealing 4.8% max hp to a boss instantly clears a stack of Enrage, rather than it waiting to update until the next cycle.
- A hero dying without reincarnating clears all stacks of Enrage from all units and delays the next cycle by 90 seconds. A hero dying with reincarnation clears 1 stack, but does not delay the cycle.

ITEMS
===============
- 7.33 Black King Bar parity for items.
- Removed Black King Bar from Signet of Destiny line, wasn't intended and wasn't working.
- Fixed Guardian Greaves line not getting Avatar's buff.

staggered unit removal so beginning a round is less hiccupy
fix to timbersaw chakram

Reworked unit garbage collection to be manual to have less crashes due to that in the future

ITEMS
===============
- Radiance damage changed back from 50 to 150.
- Glepinir damage changed from 180 to 800
- Dagon damage from 800 to 1200.
- Signet of Destiny from 800 to 1200.
