Yeah but Vengeful Heart has seven attacks at random order.
Charge-It charges at the hero
Void Spew-It launches out meteor-like projectiles that are impact detonated.
Endermite scatter- Shakes it's body and endermites fall off of it.
Endermite feast- Pulls in any living endermites and heals itself for 1/128 hp per endermite.
Void pool-Becomes invulnerable and goes to the center of the area, doing one of two attacks:
Void pull- Sucks the players towards itself before exploding, doing this three times in a row. All while dropping off more endermites.
Laser Pinwheel-Shoots lasers from segments on it's body around itself, these can hit crystals on the edge of the arena and bounce back. The lower amount of health it has, the more lasers it shoots.
Also if you convert MCD damage to Minecraft... That means that it does way more damage than the Warden and getter stronger for however strong it's opponent is (it's level goes up for however high the hero's level is). So it basically gets stronger to be on whatever level of opponent it has to face.
So, if the wither storm is so-called Maximum Level with the Vengeful Heart. And the regular Heart of Ender has 119,923.2 hp points, and the Vengeful Heart is STRONGER than the Regular Heart.
That means if it fought the wither storm it would have over 120,000 health points. OR, about the equivalent health of 200 (BEDROCK) withers. OR if Steve had 60,000 hearts.
So yeah, Vengeful Heart wins.
