seroka mob lvl up

Organic Evolution — Update
Endermen

Now progress through aging (~120 XP per Minecraft day), like Creepers, since they no longer hunt.
Only attack their aggressor: no more aggression triggered by eye contact, no more hunting Endermites.
Spared by all mobs, including Iron Golems. Only the player can still target them.
Mob Combat

A mob that kills an enemy returns to full health. Previously, they could die from attrition before reaching any progression milestone.
Mob weapons and armor are indestructible and repaired upon equipping. The "Unbreaking" property is removed from dropped items so it isn't transferred to the player.
Rewards

Kill XP doubled (50 per victim level), with a floor of 35% of the victim's milestone value taking over above level 25.
Experience orbs for the player: vanilla value at level 1, then double that value per level (×19 for a level 10 mob, ×59 for a level 30 mob).
Level Balancing

Health and movement speed: +1% → +4% per level.
Damage and attack speed: +0.5% → +2% per level.
Creeper explosion radius: +1% → +4% per level.
A level 18 skeleton goes from 23 to 33 health points and from +8.5% to +34% damage.
