Aqir

Infection · levels at 2 / 4 different pieces

Temporary pieces (summons, timed units) and copies are never Infected. A hatched Aqir starts with 0 mana and lasts 10-20 seconds.

2
All non-Aqir allies are Infected. When an Infected piece dies while another Infected copy of the same piece (any star) is still on your board, a random Aqir hatches from the body. Its level matches the strongest surviving copy.
Note: The tooltip says the hatchling matches the dying piece's level. It actually matches the strongest surviving copy, and only lasts 10-20 seconds.
4
Your Aqir pieces are Infected too. When an Aqir dies while another copy of it is on your board (Infected or not), it hatches a random Aqir one level higher than the strongest surviving copy.
Note: The tooltip says the hatchling “can be” one level higher at random. It is always exactly one level higher when an Aqir dies.
