Mossire's Mukluks question

The special ability for the legendary Mossire’s Mukluks (,s=mossire) is “Gain 5.6% movement speed while being healed”. I know variants of this question have been asked many times, but what counts as “being healed”? I have fully understood. Does Miko’s biosynthesis? Miko’s helix 2 right? Lifesteal? I assume not health regen. Any clarification would be much appreciated


Heal recive happens when a Green heart pops next to your hp bar, so anytime that heart pops means you get extra speed.

I think
