36 hp myx drones with sand veil and domain sand spawning every 2 rounds for 10 nora is cray cray. Sand generator isn't even needed anymore, two of those relics out early game is gg. Those drones need to come into play with at least half that hp.
Just to note, you do pay 30 nora upfront for the mine. That said, it could use a cd increase. Such low cooldown seems silly compared to other summon mechanics. Summon champ spam should not be encouraged.
I kind of wish they would have made this relic less passive. I know it's myx and buildup and spam, but drone spam is getting out of hand even without myx hive.
Played a game against it and sat in my opponents font the entire game, he still have enough nora for the hive to keep spawning myx. Honestly thought it was gonna be an easy win but 36 hp myx drones + SL bonus + domain sand got out of hand real quick.
