Spell Interactions in Dota 2 7.37

The breakability rules of facets, innates, and abilities have been updated
"Breakable: Yes" has been added to all abilities that are partially or fully disabled by Break
The full list of all the breakable spells is on the Patch notes here.

Abilities that are applied with attacks can no longer be blocked or reflected. For example, Tusk's Walrus Punch!

Abilities that can be unit or point targeted, but do not track their target when unit targeted can no longer be blocked or reflected. For example, Lion's Earth Spike or Sand King's Burrowstrike.

Abilities that track their target when unit targeted can be blocked or reflected. For example, Dark Seer's Ion Shell.

Abilities that can be unit targeted and displaces the caster are now blocked on ability cast instead of after displacement. For example, Huskar's Life Break

Abilities that fire a projectile at a primary target and affect an area around them now only trigger spell block and reflection on the primary target. For example, Alchemist's Unstable Concoction.

Abilities that fire individual tracking projectiles at targets to apply the same effect to all units hit now trigger spell block and reflection independently. For example, Dazzle's Poison Touch.

Unit target abilities that bounce between multiple targets will only trigger spell block and reflection on the primary target. The ability continues but subsequent targets do not trigger block/reflection. For example, Rubick's Fade Bolt.
